Best All-In-One Computers of 2026

The 24-inch 4.5K Retina display is what makes the iMac M4 feel like a different class of all-in-one. Text is sharp, photos have depth, and the 500-nit panel holds up in a bright room; if your work is writing, photo editing, or video calls, that screen earns its keep every day. The M4 chip and 16GB of unified memory keep macOS responsive in the apps we tried, and the 24-inch body is thin enough to disappear on a sideboard. It also comes in seven colors, which is more fun than the rest of this group.

We are not going to pretend the iMac is the value pick. The 256GB SSD is tight for a photo library, and Apple sells storage at purchase rather than letting you add it later. The 24-inch screen is also smaller than the 27-inch Windows machines here, which matters if you like two full documents open at once. But for an Apple household, the handoff between iPhone, iPad, and Mac is the feature that seals it, and setup is about as close to plug-in-and-go as this category gets.

If your household already runs on Apple devices, the iMac is the obvious choice; if you need 1TB of internal storage or a 27-inch canvas, the Windows picks serve you better.

The ThinkCentre neo 50a 27 is the all-in-one we point to when a small office needs one machine to run the front desk, a spreadsheet, and a video call without a tower under the counter. The 27-inch FHD IPS panel is the draw: 100Hz makes scrolling and window dragging feel smoother, and the 99% sRGB coverage keeps documents and images looking natural. We also appreciate the business-friendly bits, especially Windows 11 Pro and HDMI-in, which lets the screen double as a monitor for a laptop.

In our use, the Core i5-13420H had more headroom than the Core 3 and N100 machines here; 16GB of DDR5 memory kept a browser full of tabs and a video call from dragging. The 512GB SSD is adequate, and the memory can go to 64GB later, which gives this one a longer runway than the Dell. We also like the anti-glare, low-blue-light panel for long workdays.

The caveats are practical. There are only four USB ports, and the wired keyboard and mouse are basic, so budget for a hub or better peripherals if your desk is busy. More importantly, the reliability picture is not as clean as the Dell's: some units freeze or fail within a year, and the warranty is a one-year seller term. For a business, keep a backup plan in place and test the machine hard during the return window. It is still the best pick here for a 27-inch Windows office desktop with room to grow.

At the budget end, the IdeaCentre V100 does something the Dell cannot: it lets you add memory later. The 8GB of DDR5 is enough for email, browsing, and Office, but the machine supports up to 32GB, so it can grow if your needs do. That is the reason we reach for this one when a student or a home user needs a straightforward 24-inch desktop and does not want to replace it in two years.

The 23.8-inch FHD IPS screen is not the brightest at 250 nits, but it is sharp, anti-glare, and covers 99% sRGB; in a normal room, documents and streaming looked good. The N100 processor is the compromise. It handled everyday tasks in our use, but it is not the chip for heavy photo editing or dozens of browser tabs, and the 512GB SSD is the better half of the spec sheet. Setup is quick, and the wired keyboard and mouse are basic but serviceable. We also noticed the port layout: the USB-C and fast USB-A ports are there, but reaching them takes some blind fumbling, and there is no SD card slot. For the money, though, this is the most sensible 24-inch all-in-one here for basic home work.

If the spec sheet told the whole story, the HP 27-cr0012 wins the page. It pairs a 27-inch FHD screen with a Ryzen 7 7730U, 32GB of RAM, and a 1TB SSD, which is more memory and storage than anything else here. For a home office running huge spreadsheets, a photo library, or several virtual machines, that combination is genuinely useful, and the pop-up privacy camera is a smart touch.

But the experience does not match the numbers cleanly. The display is only 1080p at 27 inches, so text looks less crisp than on the 24-inch Dell or the 4.5K iMac; the speakers are the weakest part of the package, with static showing up in video and music playback. And the reliability risk is real: some units shut down or freeze, including one that stopped working after a day. This is not the machine we recommend as a household's only computer.

The 32GB and 1TB are real, and they make this a useful second machine for a power user who needs memory more than refinement. For most people, though, the Dell or the ThinkCentre is the safer buy; the HP's spec advantage is not worth the uncertainty.

The OmniStudio's pop-up camera is the detail we noticed first, and it is the one that makes this machine feel considered: the camera tucks away when you are not on a call, which is a nicer privacy solution than a sticky note. The 24-inch FHD IPS screen has ultra-thin bezels and a 90% screen-to-body ratio, so the picture feels larger than the footprint suggests. At 10 pounds, it is also easy for one person to move, and the EPEAT Gold and ENERGY STAR ratings are a nice bonus for a home office.

The spec sheet is where the OmniStudio asks you to compromise. The Intel N150 and 8GB of DDR5 are fine for browsing, email, and office apps, but they are not built for heavy multitasking; the 128GB of internal UFS storage is small, and the 512GB drive in the box is external, so you are managing two storage locations from day one. We also noticed the Lenovo IdeaCentre costs less and lets you add memory, which makes the HP harder to justify unless the privacy camera matters to you.

For the right buyer, someone who wants a clean, low-maintenance desk for video calls and everyday browsing, the OmniStudio is pleasant. It is not the machine for a power user, and the split storage is a daily annoyance. Choose the Lenovo V100 for raw value and the Dell for a better all-around screen.
