10 Best All-in-One Computers (September 2026) Ultimate Guide

I’ve spent the last three months testing ten of the best all-in-one computers on the market right now, and I want to share what actually holds up after daily use. These machines pack the monitor, speakers, webcam, and PC components into a single integrated device – saving desk space and cutting cable clutter compared to a traditional tower-plus-monitor setup.

If you’ve been hunting for the best all-in-one computers in 2026, you’re juggling three competing pressures: a clean desk, strong enough performance for work and play, and a screen you’ll actually enjoy staring at for eight hours a day. Our team ran each AIO through spreadsheet crunching, video calls, photo edits, and streaming to see which ones genuinely earn their place on a desk.

This guide covers Apple and Windows options across a wide price range, from the renewed 2017 iMac to the new M4 iMac, budget picks for students, and a 27-inch powerhouse for creators. I’ve flagged standout strengths and the compromises you’ll want to know about before clicking order.

We updated this article for 2026 with fresh pricing, the latest CES 2026 lineup hints, and benchmark data from third-party reviewers. Every product link points to the current Amazon listing so you can compare prices without bouncing between tabs.

Our Top 3 Tested All-in-One Computers for 2026

Comparing the Best All-in-One Computers in 2026

1. Dell 23.8″ All-in-One (Core 3 100U) – Best Value Windows for Most Buyers

This Dell is the AIO I keep recommending to friends who want a tidy, capable desktop without paying Mac money. After 30 days of daily use – spreadsheets, Slack calls, light photo edits – it never felt slow, and the white frame looks cleaner on a desk than most tower setups.

The 23.8-inch FHD panel hits 99% sRGB and gets a noticeable contrast bump over the previous generation. ComfortView Plus tones down blue light without the ugly yellow tint you get from software filters. For a desk under a window, the anti-glare coating helps a lot.

Buyers consistently praise the fast everyday performance, easy setup, and quiet operation. With 261 reviews and a 4.6-star average, this is the safest pick if you want a Windows AIO that just works.

Webcam and Audio for Hybrid Work

The 5MP+IR HDR camera tilts 0 to 20 degrees, and reviewers note it holds up well in mixed lighting. Dolby Atmos stereo speakers pump out 10W total – clear for Zoom calls, a little thin for music.

Ports and Connectivity

You get five USB ports, two HDMI ports, Ethernet, an SD card reader, and Wi-Fi 6. That HDMI-out port means you can add a second monitor without buying a dock, which is rare at this price tier.

Setup and Everyday Reliability

Setup took me about 12 minutes from box to desktop. The pop-up camera feels a little awkward the first few times, but it gives peace of mind when you’re not on a call. A small share of buyers reported the wireless keyboard and mouse not pairing out of the box – a quick USB dongle swap fixed it.

2. HP 22″ FHD All-in-One (N100) – Most Versatile

This is the AIO I’d buy for my mom. The HP 22 is small enough for a kitchen counter, light enough to move between rooms, and the N100 chip handles email, web browsing, and streaming without breaking a sweat.

The 21.45-inch FHD anti-glare display looks crisp for the price, and the dual stereo speakers are louder than I expected. It ships with Windows 11 Pro, which is unusual at this tier and gives you business-grade features like BitLocker.

Buyers love the easy setup and compact size. With 218 reviews averaging 4.4 stars, it ranks as our top entry-level pick for anyone on a tight budget.

Who This AIO Is For

If you need a secondary computer for bill paying, a kids’ homework station, or a small-office reception desk, this HP punches above its weight. The integrated UHD graphics handle 4K video playback fine.

Storage and Upgradability

HP lists support for up to 32GB of DDR5 RAM and up to 640GB of total storage across the built-in SSD and an external SSD slot. For most home users, the stock 128GB is enough once you lean on cloud storage.

Privacy and Security

The built-in webcam has a physical privacy shutter – a small thing that matters when the computer lives in a family room. Wi-Fi 6 and Bluetooth 5.3 keep wireless connections stable.

3. Apple 2017 iMac 21.5″ (Renewed) – Best Renewed Mac for Tight Budgets

I was skeptical about a renewed iMac until I plugged one in for a friend. The 2017 21.5-inch model is far from cutting-edge, but for browsing, email, and streaming it’s hard to argue with the price.

This renewed unit arrives in like-new cosmetic shape with a 1TB HDD. That’s plenty of room for photo libraries, but the spinning hard drive is noticeably slower than the SSDs in modern AIOs. Boot times stretch past 30 seconds.

With 590 reviews and a 4.0-star average, the value story holds. Reviewers consistently call out the cosmetic condition and the ability to run modern macOS versions as highlights.

Why Buy Renewed

Apple discontinued the 21.5-inch iMac a few years ago, so this is one of the cheapest ways to get a real Mac with a built-in display. Pair it with an external SSD via Thunderbolt and it gets noticeably faster.

Where It Falls Short

Don’t expect to run heavy creative apps on this machine. The Intel i5-7360U and 8GB of DDR4 are fine for everyday tasks but choke on big Photoshop files. Also, AppleCare cannot be purchased for this older unit.

macOS Compatibility

Most units can run macOS Ventura after a clean install, but older factory software can block upgrades. Plan on doing a fresh install with a USB installer when you receive it.

4. Apple 2024 iMac M4 24-inch – Editor’s Choice / Best Mac

This is the all-in-one I keep coming back to. The M4 iMac is thin, fast, and the screen is the best you can buy in this category. After two months of daily use, I never felt the need to plug in an external monitor.

The 24-inch 4.5K Retina display hits 500 nits of brightness and a billion colors. In my living room with the windows open, the screen stayed readable – something I cannot say for most Windows AIOs in this tier.

With 215 reviews and a 4.8-star average, this is the highest-rated AIO on our list. The thin colorful design livens up any room, and Apple Intelligence integration is genuinely useful for quick summaries.

Performance and Apple Intelligence

The M4 chip’s 10-core CPU handles everything from 4K video edits in Final Cut Pro to large Logic projects without breaking a sweat. Apple Intelligence uses the Neural Engine for on-device AI tasks like writing tools and image generation.

Webcam, Mics, and Speakers

The 12MP Center Stage camera is the best webcam on any AIO I’ve tested. Three studio-quality mics pick up voices cleanly across a small conference table. The six-speaker Spatial Audio system is good enough to skip external speakers for casual listening.

Ports, Storage, and Connectivity

Up to four Thunderbolt 4 ports, Wi-Fi 6E, and Bluetooth 5.3 are all here. The base 512GB SSD fills up fast on a creative machine, so plan on external storage or the higher-capacity configuration. Note: there are no USB-A ports, so legacy accessories need a hub.

5. Apple 2020 iMac 27-inch 5K – Best Big-Screen Mac

If screen real estate matters more than bleeding-edge silicon, the 27-inch 5K iMac is still a workhorse. I used one as my primary editing machine for over a year and never missed an external monitor.

The 5120-by-2880 Retina display makes photo edits feel precise, and text looks print-sharp. The 6-core Intel i5 and Radeon Pro 5300 are aging, but for 4K video timelines and Lightroom catalogs they handle the workload well.

With 475 reviews averaging 4.6 stars, this iMac remains a favorite among creators on a budget. Just be aware that AppleCare cannot be purchased after the fact on this older model.

Who Should Still Buy It

Content creators who want a 5K canvas without buying a separate display will love this iMac. The dedicated Radeon Pro graphics still accelerate many creative apps.

What About macOS Support

Intel-based Macs have a shorter software runway than M-series machines. If you plan to keep this iMac for five-plus years, the M4 model is a safer long-term bet.

Ports and Connectivity

Two Thunderbolt 3 ports, four USB-A ports, Ethernet, and an SD card slot make this iMac one of the most flexible AIOs for accessory lovers. No dongles required.

6. Lenovo 24″ FHD AIO (N100, 16GB) – Best Office Workhorse

When I tested this Lenovo for a remote-work setup, the thing that stood out was the Ethernet port. In an age of flaky home Wi-Fi, a wired network connection on an AIO at this price is unusual.

The 16GB of DDR4 RAM is double what similarly priced competitors ship, and the 256GB PCIe SSD boots Windows 11 Pro in under 15 seconds. The 23.8-inch FHD IPS anti-glare display hits 99% sRGB at 250 nits – good for spreadsheets and document work.

With 146 reviews and a 4.3-star average, buyers appreciate the Ethernet port, multiple USB ports, and Windows 11 Pro for business use.

Ports and Wired Networking

You get two USB-A Hi-Speed ports, two USB-A 10Gbps ports, HDMI-out, Ethernet, and a headphone combo jack. The Vent-Hear design improves airflow, and the white frame looks tidy in a small office.

Keyboard Quirks

A handful of buyers reported non-standard function key defaults and occasional UK-style keyboards. If your typing speed depends on muscle memory, plan to remap the function row in Windows.

7. HP 24″ OmniStudio AIO (N150) – Best Home and Student

This HP OmniStudio is the AIO I’d put in a dorm room. The ultra-thin bezels make the 24-inch screen feel bigger than it is, and the pop-up camera is a privacy win for shared spaces.

The Intel N150 chip and 16GB of LPDDR5 RAM handle browser tabs, Google Docs, and Zoom calls with room to spare. SSD storage boots the machine in about 12 seconds, and EPEAT Gold registration means it’s a relatively sustainable choice.

With 146 reviews and a 4.4-star average, customers generally view the OmniStudio as great value for everyday productivity. The keyboard layout draws complaints for being non-standard.

Display and Design

The 90% screen-to-body ratio gives this AIO a modern look that punches well above its price. The white frame fits in a kitchen nook or a child’s bedroom without feeling out of place.

Connectivity Quirks

A small number of buyers report needing to download a fresh Wi-Fi driver from HP’s support page to get reliable wireless connectivity. Plan for that 10-minute update before your first Zoom call.

Privacy Features

The pop-up privacy camera tucks away when not in use, and dual microphones with noise reduction pick up voices clearly during video calls.

8. Dell Inspiron 5430 AIO (Core 5 120U) – Best Mid-Range Windows

This Dell is the AIO I’d recommend to anyone who wants a real step up from entry-level hardware. The Core 5-120U breezes through spreadsheets with thousands of rows and handles dozens of Chrome tabs without breaking a sweat.

The 23.8-inch FHD display supports Dell ComfortView Plus for blue-light filtering, and the dual 5W speakers with Dolby Atmos sound surprisingly room-filling. The stand has a built-in keyboard parking space – a small touch that declutters the desk when the computer is idle.

With 81 reviews and a 4.4-star average, customers view the Inspiron 5430 as smooth, fast, and stylish for business and student work.

Upgradability and Repair

Unlike most AIOs, this Dell allows user-accessible RAM upgrades. The 8GB DDR4 configuration can be expanded without sending the unit in for service – a real plus for anyone who plans to keep the machine for five-plus years.

Webcam and Audio

The 5MP camera with Wide Dynamic Range tilts from -5 to 25 degrees. Dual 5W Dolby Atmos speakers sound bigger than they look. Reviewers note occasional stability and Wi-Fi drops, so keep your Wi-Fi drivers current.

9. Lenovo ThinkCentre AIO (Core i7-13620H) – Best Business

This is the AIO I’d spec for a small-business front office. The 10-core i7-13620H chews through multitasking, and the ThinkShield security suite is a real differentiator if your company handles sensitive data.

The 27-inch FHD IPS touch display hits 99% sRGB at 300 nits with a 100Hz refresh rate. The 5MP IR camera with AI noise suppression and face tracking makes this a Zoom-room star, and Windows 11 Pro comes pre-installed.

With 61 reviews and a 4.5-star average, business users praise the i7 performance, sharp 27-inch touch display, and strong security features.

Security and Manageability

ThinkShield includes fTPM, a camera e-shutter, and a Kensington lock slot. IT departments will appreciate that Windows 11 Pro supports BitLocker and remote management out of the box.

Performance Headroom

The i7-13620H has 10 cores and 16 threads, which gives this AIO serious headroom for spreadsheets, code compilation, and VM workloads. Integrated graphics keep the price in check but limit gaming.

10. Dell 27″ All-in-One (Core 7 150U) – Best 27-inch Windows

If you want a 27-inch Windows AIO that doesn’t feel compromised, this Dell delivers. The Core 7 150U’s 10 cores run cool and quiet, and the 1TB SSD means you won’t be hunting for external storage right away.

The 27-inch FHD IPS display hits 99% sRGB with ComfortView Plus for blue-light reduction. Dell’s innovative stand has a built-in keyboard parking space that keeps the desk tidy when you’re not typing.

With 81 reviews and a 4.4-star average, owners praise the powerful performance, vivid display, and clean compact design.

Performance and Storage

The Core 7 150U hits 5.4GHz under boost and handles photo edits, large spreadsheets, and dozens of browser tabs with ease. The 1TB SSD is generous for the price tier and a real differentiator versus the 256GB and 512GB competitors.

Webcam, Audio, and Connectivity

The 5MP+IR HDR camera tilts 0 to 20 degrees for the right framing during video calls. Dual Bluetooth speakers with Dolby Atmos spatial sound fill a small office. Wi-Fi 6 and Bluetooth keep wireless accessories paired reliably.

Subscription Software Caveat

Dell moved Office to a subscription model, so the machine ships without a permanent Office license. Plan for Microsoft 365 if you need Word, Excel, and PowerPoint.

How to Choose the Best All-in-One Computer for Your Needs

Buying an AIO is a balance between screen size, performance, and how long you plan to keep the machine. Here are the five questions our team asks before recommending a specific model.

What screen size and resolution do you need?

A 22-inch or 24-inch FHD display works for tight desks and kitchen counters. For spreadsheets, photo editing, or split-screen multitasking, a 27-inch 4K or 5K panel is worth the upgrade. The 4.5K Retina display on the M4 iMac is in a class of its own.

Which CPU and RAM should you target?

For browsing, email, and streaming, an Intel N100 or N150 with 8GB of RAM is plenty. For heavier multitasking, photo edits, or light video work, aim for an Intel Core 5, Core 7, or Apple M4 with 16GB. The Dell Inspiron 5430 and Lenovo ThinkCentre are good mid-tier picks.

Can you upgrade RAM and storage later?

Most AIOs solder the RAM to the motherboard, making upgrades impossible. The Dell Inspiron 5430 is one of the few exceptions. Plan storage carefully: a 512GB SSD is a sensible minimum for most users, with 1TB or external storage for big media libraries.

Do you need a touchscreen?

Touchscreens are nice for casual scrolling and creative work, but they add cost and reflect more light. The Lenovo ThinkCentre AIO and the Lenovo Yoga AIO line are the strongest touchscreen picks. If you don’t plan to touch the screen often, save money and skip the feature.

How important are webcam and speakers?

If you spend hours on Zoom, the 12MP Center Stage camera on the M4 iMac is in a class of its own. The Dell OmniStudio and Lenovo ThinkCentre both have 5MP cameras with Windows Studio Effects. For speakers, the M4 iMac’s six-speaker Spatial Audio is the standout.

All-in-One vs Mini PC Plus Monitor

Wirecutter’s analysis shows a Mac Mini M4 plus a 4K monitor bundle often lands noticeably cheaper than a comparable AIO. If you value upgradability, a mini PC is a smarter buy. If you want a single-cable setup with bundled peripherals, AIOs win.

What About Repairs and Lifespan?

Plan on three to five years for a typical AIO. Apple machines tend to last longer thanks to macOS support windows. Most AIOs are not user-repairable beyond RAM, so factor in replacement rather than repair.

Frequently Asked Questions

Final Verdict: Which All-in-One Should You Buy in 2026?

After three months of testing, our team landed on a clear hierarchy. For most people who want the best mix of display, performance, and design, the Apple 2024 iMac M4 is the best all-in-one computer in 2026. The 4.5K Retina display is genuinely stunning, the M4 chip chews through everything from Final Cut timelines to Logic sessions, and the 12MP Center Stage webcam is the best on any AIO we’ve tested.

If you’re a Windows user or want to spend less, the Dell 23.8-inch All-in-One (Core 3 100U) is the safe pick. It looks clean on a desk, performs smoothly for everyday work, and the 5MP webcam holds up well in mixed lighting. For buyers on a tight budget, the HP 22-inch FHD AIO is the cheapest path into a real desktop.

For businesses and creators, the Lenovo ThinkCentre AIO (i7-13620H) brings ThinkShield security and a 27-inch touch display, while the Dell 27-inch AIO (Core 7 150U) gives you a vivid 27-inch panel with a 1TB SSD. Either is a strong choice if you need a big-screen Windows AIO.

Whichever model you choose, buy the specs you need on day one – most AIOs do not allow mid-life upgrades. For more comparisons, check out our best desktop computers for video conferencing roundup, or browse our best home gym all-in-one systems guide if you’re building out a smaller space.
