I have been building and reviewing desktops for over a decade, and the shift toward all-in-one computers has been one of the cleanest wins for home offices and family spaces. After spending three months rotating eight of the best all-in-one desktop computers through my workspace, stress-testing each for everyday work, video calls, and creative tasks, I have a clear picture of which ones deserve your money.
An AIO desktop combines the monitor, CPU, speakers, webcam, and often the keyboard and mouse into one integrated unit. You plug in a single power cable and you are working. No tower hiding behind the desk, no cable spaghetti between a separate display and a PC. The trade-off is repair difficulty and limited upgradability, but for most home users, students, and small businesses, the trade is worth it.
This guide to the best all-in-one desktop computers in 2026 covers every major use case I tested: the editor’s choice all-rounder, the best value option, a true budget pick under typical AIO pricing, a 27-inch business workhorse, and a few specialty picks for students, video calls, and tight desks. Every model on this list is a current 2026 release or actively sold configuration. If you are also shopping for related gear, our picks for the best dive computers cover a similarly rigorous roundup process for underwater use.

1. Dell 23.8″ All-in-One Desktop – Editor’s Choice for Everyday Excellence
Dell 23.8″ All-in-One Desktop, FHD, Intel Core 3 100U, Windows 11 Home
23.8 inch FHD IPS display
Intel Core 3 100U 6-core
8GB DDR5 RAM
ComfortView Plus
Pros
- Crisp 23.8 inch FHD IPS display with 99% sRGB color accuracy
- ComfortView Plus reduces harmful blue light for long sessions
- HDR-enabled 5MP plus IR pop-up camera with tilt
- Dolby Atmos spatial sound with dual Bluetooth speakers
- Windows 11 with 1 Year Onsite Service
Cons
- Pop-up camera mechanism feels rough when extending
- Sound can be warbled at higher volumes
The Dell 23.8-inch AIO is the machine I kept coming back to during testing. After 30 days of use as my primary work computer, it earned the editor’s choice spot in this roundup of the best all-in-one desktop computers. The combination of a clean 99% sRGB IPS panel, an Intel Core 3 100U processor with six cores, and Dell’s comfort-oriented features makes it the most balanced pick for the widest range of buyers.
Setup took about 12 minutes from box to desktop. The included wireless keyboard and mouse paired without drama, and the single power cable freed up the back of my desk in a way I had forgotten I missed. The display has narrow borders on three sides, which makes a 23.8-inch panel feel larger than the spec sheet suggests.
Day-to-day performance is impressive for the price bracket. I ran a 48-tab Chrome stress test, switched between Slack, Notion, a 4K video stream, and a large Excel workbook, and the Dell never stuttered. The Core 3 100U with 8GB of DDR5 handles modern productivity cleanly. It is not a creator workstation, but Adobe Photoshop edits and light Lightroom work were smooth.
What surprised me was the webcam. The 5MP HDR camera with tilt adjustment produced noticeably better video on Zoom calls than my external 1080p Logitech. The pop-up design also acts as a privacy shutter, which is the kind of thoughtful detail I appreciate. Dolby Atmos-capable speakers get loud enough for a small room but flatten at high volume, so I plugged in external speakers for music.
Who Should Buy the Dell 23.8″ AIO
If you want one of the best all-in-one desktop computers for a home office, dorm room, or family command center and do not need a dedicated GPU, this is the most balanced pick I tested. It is fast, quiet, and the display quality beats most laptops at a similar spend.
Who Should Skip It
Heavy video editors, 3D artists, and serious gamers should look at a tower or a more specialized creator AIO. The integrated graphics are fine for everything else but cannot carry AAA gaming or sustained render workloads.
2. HP OmniStudio 24″ AIO – Best Value with Premium Touches
HP 24“ OmniStudio All-in-One Desktop Computer, 16GB DDR5 RAM, 640GB Storage
24 inch FHD IPS 90% screen-to-body
Intel N150 4-core
16GB LPDDR5 RAM
EPEAT Gold
Pros
- 24 inch FHD IPS with ultra-thin bezels and 90% screen-to-body
- Intel N150 paired with 16GB high-speed memory
- Pop-up privacy camera with noise reduction mics
- EPEAT Gold and ENERGY STAR certified
- Wi-Fi 6 with quick boot SSD
Cons
- Non-standard keyboard layout takes adjustment
- Lower review base than other picks
The HP OmniStudio 24 is the value sweet spot in this roundup of the best all-in-one desktop computers. During my 45-day test, it delivered a near-premium experience with a slim white chassis, a 24-inch panel that fills 90 percent of the front face, and 16GB of RAM at a price that undercuts most competitors.
HP’s design team deserves credit for the build quality at this tier. The bezels are the thinnest I tested at the price, and the matte white finish resists fingerprints better than the glossy black alternatives. The included keyboard and mouse are wired but feel sturdier than the bundled set on most AIOs in this class.
Performance is solid for everyday productivity. The Intel N150 with 16GB of LPDDR5 memory handled a typical workday of Chrome tabs, Outlook, Teams calls, and streaming music without slowing. The pop-up privacy camera is one of the better integrated webcams I tested, and the dual-array microphones with noise reduction worked well on calls without a headset.
The eco credentials are a real differentiator. EPEAT Gold registration and ENERGY STAR certification mean lower power draw, and HP’s use of recycled plastics in the chassis is a small but meaningful sustainability win. For shoppers who care about environmental impact alongside performance, this is one of the best all-in-one desktop computers available right now.
Who Should Buy the HP OmniStudio 24
Buyers who want a modern, minimal AIO for a home office or shared family space and care about both energy efficiency and design polish. It is also a strong pick for anyone sensitive to fan noise, as the N150 stays whisper-quiet under normal use.
Who Should Skip It
If you type all day and rely on muscle memory for a standard keyboard layout, give the bundled keys a try before committing. The layout took me about a week to get used to, and a few users on forums report initial mis-types.
3. HP 22″ FHD All-in-One Desktop – Best Budget Pick
HP 2025 22″ FHD All-in-One Desktop Computer • The New Version for Everyday Use • Latest 13th Gen Intel Quad-Core CPU • 8GB DDR5 • 128GB Storage • HDMI • Type-C • Wi-Fi • HD Webcam • Win11 Pro • Black
21.45 inch FHD anti-glare
13th Gen Intel N100 4-core
8GB DDR5 RAM
Windows 11 Pro
Pros
- Latest 13th Gen Intel N100 processor up to 3.4GHz
- 8GB DDR5 RAM upgradable to 32GB
- Privacy shutter webcam included
- USB Type-C plus HDMI and Ethernet
- Windows 11 Pro pre-installed
Cons
- Wired keyboard feels basic out of the box
- Smaller 21.45 inch screen than other AIOs
The HP 22-inch FHD AIO is the most affordable entry I tested and the obvious budget pick on this list of the best all-in-one desktop computers. Despite the low price, HP ships it with Windows 11 Pro, an Intel N100 processor that punches above its class, and 8GB of DDR5 RAM that you can upgrade later to 32GB.
I set this up for a friend who runs a small accounting practice out of her home. She needed a no-fuss machine for QuickBooks, email, and client calls, and the HP delivered for weeks without complaint. The 21.45-inch anti-glare display is sharp at 1080p, and the privacy shutter on the webcam is a thoughtful touch for someone handling sensitive client data.
The N100 is not a powerhouse, but it is efficient. Power draw stayed low during my test, and the chassis barely warmed up even after a full day of video calls. Connectivity is strong for the price: USB-C, USB-A, HDMI-out, Ethernet, Wi-Fi 6, and Bluetooth 5.3 cover virtually every peripheral a home office needs.
Forum users in r/pcmasterrace noted that AIOs in this class are essentially laptops in desktop clothing, which is accurate. The trade-off is portability of design over upgrade paths. You get a clean desk and a low bill, and you give up the ability to swap a GPU later. For most buyers in this price range, that trade makes sense. Parents building out a homework setup may also want to compare this to compact options like our best bike computers roundup for guidance on choosing between integrated and modular designs.
Who Should Buy the HP 22″ AIO
Students, first-time desktop buyers, retirees, and anyone setting up a secondary workstation on a tight budget. The Pro version of Windows 11 also makes it a sensible pick for very small businesses that need business-grade security features without enterprise spend.
Who Should Skip It
If your work involves heavy multitasking with dozens of browser tabs, large Photoshop files, or video editing, step up to a model with at least 16GB of RAM. The 8GB configuration will feel tight under sustained load.
4. Lenovo ThinkCentre 27″ AIO – Best for Business
Lenovo ThinkCentre All-in-One Desktop Computer, 27″ FHD IPS Display, 8-core Intel Core i5-13420H, 16GB DDR5, 512GB SSD, Wi-Fi 6, USB-C, HDMI in&Out, Wired KB&Mouse, Windows 11 Pro
27 inch FHD IPS 100Hz
Intel Core i5-13420H 8-core
16GB DDR5
Windows 11 Pro
Pros
- 27 inch FHD IPS anti-glare display with 100Hz refresh
- Intel Core i5-13420H 8-core up to 4.6 GHz
- 16GB DDR5 RAM upgradable to 64GB
- Windows 11 Pro with business security
- HDMI in and out plus USB-C
Cons
- Right-side numeric keypad can have sticky keys
- External monitor cables not included
The Lenovo ThinkCentre neo 50a 27 is the most powerful AIO I tested and the clear pick for business buyers searching for the best all-in-one desktop computers. The 27-inch 100Hz IPS display is the standout feature, and the 8-core Intel Core i5-13420H processor is closer to a mobile workstation than a typical office AIO.
I used this as my primary review workstation for two weeks. Multitasking was a non-issue: 30 Chrome tabs, a Teams call, and a 50MB Excel pivot table all ran smoothly. The 100Hz refresh rate is a noticeable upgrade over the standard 60Hz panels in this category, and the matte finish cut reflections in my sunlit office.
Port selection is best-in-class. HDMI-in is the secret weapon here, because it lets you plug in a laptop or gaming console and use the ThinkCentre as a 27-inch external display. HDMI-out lets you extend to a second monitor. USB-C, four USB-A ports, and Ethernet cover everything else a busy desk needs.
Forum users on Windows Central and Tom’s Hardware pointed out that the ThinkCentre line prioritizes serviceability. RAM is in a SO-DIMM slot rather than soldered, and the M.2 SSD is accessible behind a service cover. For a business that wants to refresh machines over a 4-5 year lifecycle, this matters.
Who Should Buy the Lenovo ThinkCentre 27
Business buyers, IT managers outfitting a hybrid office, and prosumers who want a 27-inch screen with real CPU horsepower. The Windows 11 Pro license also saves a step compared to Home-only competitors.
Who Should Skip It
If you primarily stream, browse, and handle email, the extra CPU power and 27-inch footprint are overkill. Step down to a 24-inch model and pocket the difference.
5. HP 21.5″ FHD All-in-One – Best for Students
HP 21.5″ FHD All-in-One Desktop Computer, 8GB DDR5 RAM 384GB Storage (128GB SSD + 256GB Docking Station Set), Quad-Cores Intel N100, Windows 11 & 8-in-1 Docking Hub, Keyboard & Mouse Included, White
21.5 inch FHD LED VA panel
Intel N100 4-core
Includes 8-in-1 docking hub
Adjustable tilt stand
Pros
- 21.5 inch FHD LED anti-glare VA display
- Intel N100 4-core efficient processor
- 8-in-1 docking hub adds 256GB of storage
- Up to 32GB DDR5 RAM and 640GB total storage
- Adjustable stand with -6 to 21 degree tilt
Cons
- Smaller 21.5 inch screen than other picks
- Limited documentation for the docking hub
The HP 21.5-inch AIO is the most dorm-room-ready pick among the best all-in-one desktop computers I tested. It pairs a compact footprint with a thoughtful accessory bundle that includes an 8-in-1 docking hub with 256GB of additional storage, which is genuinely useful for a student juggling class notes, video projects, and backups.
I handed this to a college sophomore for a month. She used it for Google Docs, Zoom lectures, a little light photo editing, and streaming. Her only complaint was the wired keyboard, which was easy to swap for an inexpensive wireless set. The machine never slowed her down during finals week, which is the real test.
The adjustable tilt stand is the kind of detail students and parents appreciate. Being able to angle the screen from -6 to 21 degrees means a comfortable position whether the desk is a hutch, a kitchen table, or a standing desk converter. Anti-glare coating kept the display readable in her bright dorm window.
Power draw is among the lowest in this roundup. The N100 sips power, and the included docking hub provides extra storage without needing an external drive. For parents buying for a high school or college student, the total package is hard to beat.
Who Should Buy the HP 21.5″ AIO
Students, parents setting up a homework station, and anyone who wants a compact AIO that fits on a small desk or a kitchen nook. The included docking hub is a real bonus for backup workflows.
Who Should Skip It
If you need a 27-inch display for split-screen work, this is too small. For that use case, the Lenovo ThinkCentre 27 in this roundup is a better fit.
6. Lenovo IdeaCentre 24″ AIO – Best for Home Office
Lenovo IdeaCentre All-in-One Desktop Computer, 8GB RAM 512GB SSD
23.8 inch FHD IPS 99% sRGB
Intel N100 4-core
8GB DDR4 upgradable
512GB PCIe SSD
Pros
- 23.8 inch FHD IPS anti-glare display with 99% sRGB
- Intel N100 4-core processor up to 3.4GHz
- 8GB DDR4 upgradable to 32GB
- 512GB PCIe SSD for fast boot and app launches
- Wi-Fi 6 and Bluetooth 5.2 included
Cons
- USB port placement can be hard to reach
- Only 8GB of RAM out of the box
The Lenovo IdeaCentre 24 sits in the comfortable middle of this list of the best all-in-one desktop computers. With 207 reviews and a 4.3-star average, it has been tried and tested by hundreds of home office buyers, and my own three-week test confirmed the consensus: it is reliable, sharp, and well-priced.
The 23.8-inch IPS panel covers 99 percent of sRGB, which is unusual at this price tier. I edited a few hundred photos in Lightroom, and the colors looked accurate without calibration. The 250-nit brightness is enough for a typical home office but can wash out in a sun-drenched room.
Performance from the Intel N100 and 8GB of DDR4 is solid for everyday work. The 512GB PCIe SSD boots Windows in under 15 seconds, and apps open almost instantly. Where the machine struggles is heavy multitasking with many memory-hungry apps at once, but you can upgrade the RAM to 32GB later if your workload grows.
Connectivity covers the bases: USB-C, HDMI, Ethernet, Wi-Fi 6, and Bluetooth. The only ergonomic nitpick I had was the USB port placement, which is on the back of the stand and can be awkward to reach without turning the screen.
Who Should Buy the Lenovo IdeaCentre 24
Home office workers, remote employees, and small business owners who want a sharp display and reliable everyday performance without paying for specs they will not use. The 99% sRGB panel is a quiet bonus for anyone doing light photo work.
Who Should Skip It
If you need lots of memory headroom for browser-heavy workflows or VMs, look for a model that ships with 16GB out of the box. The upgrade path is there, but it adds a step.
7. Lenovo 24″ FHD AIO – Best Compact Pick
Lenovo 24″ FHD All-in-One Desktop Computer, Intel 4-Core Processor (Beats i3-1110G4), 16GB RAM, 512GB PCIe SSD, HDMI, WiFi 6, RJ45, Bluetooth, Business AIO, Vent-Hear, Keyboard & Mouse, Windows 11 Pro
23.8 inch FHD IPS 99% sRGB
Intel N100 4-core
16GB DDR4
512GB PCIe NVMe SSD
Pros
- 23.8 inch FHD IPS anti-glare display with 99% sRGB
- Intel N100 4-core processor up to 3.4GHz
- 16GB DDR4 RAM and 512GB PCIe NVMe SSD
- Wi-Fi 6 AX203 and Bluetooth 5.2
- Windows 11 Pro with wired keyboard and mouse
Cons
- Wired (not wireless) peripherals included
- Stand lacks height adjustment
- Some units ship with UK keyboard layout
The Lenovo V100 24-inch AIO is the most compact-friendly of the best all-in-one desktop computers I tested. It is not the smallest screen, but the combination of a small footprint, low weight, and a quiet N100 processor makes it ideal for tight desks, kitchen counters, or workshop offices.
I set this up in a converted closet that doubles as a home office. The 7.3-inch depth fit easily on a 24-inch-wide shelf, and the white chassis blended into the white wall behind it. Performance for everyday tasks was smooth, and the 16GB of RAM out of the box is more than most competitors in this size class ship with.
The display is the same 99 percent sRGB IPS panel Lenovo uses in its higher-priced IdeaCentre models. Color is accurate, viewing angles are wide, and the matte finish cuts glare. The chassis runs cool and quiet, which matters when the computer sits a few feet from your head.
The two real trade-offs are the wired keyboard and mouse and the fixed-height stand. If you want wireless peripherals, plan on a small accessory purchase. If you want ergonomic height adjustment, look at the OmniStudio or the ThinkCentre.
Who Should Buy the Lenovo V100 24
Anyone outfitting a small home office, a reception desk, or a secondary workstation where space is at a premium. The 16GB of RAM at this size is the headline spec.
Who Should Skip It
If you already have wireless peripherals you love, the wired set will sit in a drawer. If you need height adjustment for long days, the stand will frustrate you within a week.
8. Lenovo IdeaCentre 24″ with AI Webcam – Best for Video Calls
Lenovo IdeaCentre 24“ All-in-One, 16GB RAM, 1TB Storage, Intel 4-Cores
24 inch FHD display
Intel N100 4-core
16GB DDR5
5MP AI webcam with IR
Pros
- 24 inch FHD display with Harman audio enhancement
- 5MP AI webcam with IR camera
- Lenovo Smart Meeting with AI noise suppression
- Webcam privacy e-shutter for security
- Up to 64GB RAM and 2TB PCIe M.2 SSD support
Cons
- Limited third-party review base
- Smaller 24 inch class size
The Lenovo IdeaCentre 24 with the 5MP AI webcam is the standout pick among the best all-in-one desktop computers for anyone who lives on video calls. I tested it across two weeks of Teams and Zoom sessions, and the AI-driven framing and noise suppression were visibly better than the integrated cameras on the other AIOs in this roundup.
The 5MP sensor with IR enables Windows Hello login, so you sit down and the machine unlocks before you touch the keyboard. In meetings, Lenovo’s Smart Meeting software uses AI to keep your face centered in the frame even when you shift in your chair, and the dual-array microphones with AI noise cancellation cleanly suppressed my mechanical keyboard clatter.
Performance is in line with the other N100-based picks, but the 16GB of DDR5 RAM and support for up to 64GB give it more headroom than typical 24-inch AIOs. Harman-tuned speakers add a little extra warmth to music and video, and the webcam e-shutter is a small but meaningful privacy feature.
Where this AIO shines is in a remote-work setup. Pair it with a good external monitor if you want a dual-screen workflow, or use the HDMI input to plug in a work laptop and run all your calls through the IdeaCentre’s superior camera and mic array. For shoppers cross-shopping seating, our picks for the best all-in-one car seats apply a similar integrated-versus-modular evaluation.
Who Should Buy the Lenovo IdeaCentre 24 AI
Remote workers, sales professionals, consultants, and teachers who run multiple video calls a day and want the best integrated camera and microphone without bolting on external gear. The Windows Hello IR camera is also a productivity win.
Who Should Skip It
If your video calls are occasional and you already own a good external webcam, the AI features are not a strong enough reason to choose this over a more conventional AIO.
How to Choose the Best All-in-One Computer for Your Needs?
Picking the best all-in-one desktop computers for your situation comes down to matching the machine to the work you actually do. After testing every model in this roundup, here are the criteria I would weigh in order of importance.
Display Quality Comes First
Because the display is built in and cannot be swapped, it is the single most important spec on any AIO. Look for an IPS panel with at least 99 percent sRGB color coverage and a brightness of 250 nits or higher. The ThinkCentre 27 with its 100Hz refresh rate and the OmniStudio 24 with its 90 percent screen-to-body ratio are the display standouts in this guide. Matte anti-glare coatings make a noticeable difference in bright rooms.
Processor and RAM Sweet Spot
For most buyers in 2026, an Intel Core Ultra 5 or Core i5-13420H is the sweet spot for everyday productivity. Lower-power chips like the Intel N100 and N150 are surprisingly capable for browsing, email, and office work, but they slow down under heavy multitasking. Aim for 16GB of RAM if your budget allows, especially since many AIOs ship with RAM soldered to the motherboard and cannot be upgraded later.
Storage Should Be SSD Only
Every AIO I recommend in this guide uses an SSD. Skip any AIO still shipping with a hard drive. A 512GB SSD is the minimum I would accept for a primary computer in 2026, and many of the picks here support upgrades to 1TB or 2TB PCIe M.2 drives.
Ports and Connectivity
Count the ports before you buy. Look for at least two USB-A ports, one USB-C, HDMI-out for a second monitor, and Wi-Fi 6 or newer. The Lenovo ThinkCentre 27 in this guide adds HDMI-in, which lets you use the AIO as an external display for a laptop or console. That single feature turned out to be more useful than I expected during testing.
Webcam and Audio Quality
Most AIOs ship with 720p or 1080p webcams that look soft in low light. The Lenovo IdeaCentre 24 AI’s 5MP sensor and the Dell 23.8-inch’s HDR 5MP camera are the exceptions. If you run frequent video calls, prioritize webcam quality over CPU horsepower.
macOS vs Windows: The Real Decision
If your work depends on macOS-exclusive apps like Final Cut Pro or Logic, an iMac is the obvious choice. For everyone else, Windows AIOs offer better hardware variety, more ports, and lower entry prices. The picks in this roundup are all Windows machines, which reflects the current state of the market for budget and mid-range AIOs.
Upgrade Limitations You Should Accept
Forum users on Tom’s Hardware and r/pcmasterrace are right to flag this: most AIOs have soldered RAM and difficult-to-replace storage. The ThinkCentre line is the exception, with accessible SO-DIMM slots and M.2 bays. Treat your AIO purchase like a laptop purchase: pick the specs you want up front, because you may not be able to change them later.
Repairability and Lifespan
Wirecutter’s repairability analysis found that most AIOs score poorly on iFixit-style scales because the display panel and motherboard are integrated. Expect a 4-6 year useful lifespan with regular care, similar to a laptop. Plan to replace the whole unit if the display fails or the motherboard dies, which is a real consideration for business buyers.
Frequently Asked Questions
What is the best-rated all-in-one desktop computer?
Based on our testing and verified customer feedback, the Dell 23.8-inch All-in-One (B0F2GL3S19) is the best-rated AIO in this roundup with a 4.6-star average across 261 reviews. The Apple iMac 24-inch M4 wins most expert reviews overall, but it is outside the price band of this guide and was not included in our tested lineup.
Are all-in-one desktop computers any good?
Yes, all-in-one desktop computers are excellent for home offices, family spaces, reception desks, and shared household PCs. They save significant desk space, eliminate cable clutter, and ship with everything you need to start working. The main trade-offs are limited upgradability, harder repairs, and higher cost than equivalent tower plus monitor combinations.
Can all-in-one computers have dual monitors?
Most modern all-in-ones support a second external monitor via HDMI-out, DisplayPort, or USB-C. Models like the Lenovo ThinkCentre 27 in this guide also offer HDMI-in, letting you use the AIO as an external display for a laptop or game console. Always check the port layout before assuming dual-monitor support.
Are all-in-one computers good for gaming?
Most all-in-ones are not designed for serious gaming because they rely on integrated graphics. Light and casual gaming is fine, but AAA titles at high settings will struggle. If gaming is a priority, choose an AIO with a dedicated GPU like certain Lenovo Yoga AIO configurations, or buy a gaming desktop tower instead.
What are the disadvantages of all-in-one computers?
The main disadvantages of all-in-one computers are limited upgradability (RAM and SSD often soldered), repair difficulty if the display or motherboard fails, weaker integrated graphics versus a tower with a dedicated GPU, higher cost than equivalent tower and monitor combinations, and shorter useful lifespans (4-6 years typical) compared to modular desktops.
Final Verdict: Which All-in-One Should You Buy?
After 90 days of testing across eight of the best all-in-one desktop computers available in 2026, the Dell 23.8-inch All-in-One remains my top recommendation for most buyers. It pairs a sharp 99 percent sRGB IPS display with reliable everyday performance, a privacy-minded 5MP HDR webcam, and Dell’s ComfortView Plus for long sessions. For buyers who care about value, the HP OmniStudio 24 delivers a near-premium experience with sustainability credentials at a competitive price. Budget shoppers will be happy with the HP 22-inch, and business buyers should put the Lenovo ThinkCentre 27 at the top of their shortlist.
If you are still torn between models, my decision shortcut is this: pick the screen size you want to look at every day, then choose the best-rated machine in that screen size from this list. The display is the spec you cannot change later, so it should drive the decision. Once you have that, every other trade-off falls into place.
