The best budget all-in-one computer
Students and budget-minded users alike will appreciate the HP Chromebase. Basically a Chromebook in all-in-one form, this combines the benefits of a Chromebook – great value, great performance, great design – with the advantages of an all-in-one including having a big display in a smaller desktop footprint.
During our tests, it proved to be a capable machine that looks great and comes with thoughtful design features you’ll find useful. We often had it running 20 or more tabs at the same time, and it handled those without signs of a slowdown. Meanwhile, the built-in are impressive in their own right.
All-in-one PCs are usually expensive, but this one is an exception. And, a great one at that, especially for families, college students, and office workers whose tasks are mostly done on the Google Chrome browser.

The best all-in-one computer for creatives
The HP Envy 34 all-in-one computer is undeniably powerful, offering an excellent iMac alternative to Windows users who want outstanding design, fantastic features, and great performance for a relatively affordable price. Our coveted five-star rating is rarely given, which should speak volumes about how impressive it is. That's despite the fact that it runs a last-gen Intel processor and a mobile GPU.
Among the many things we appreciate here are its movable 16MP webcam and excellent selection of ports. On test, however, it's its stunner of a display that hogs the spotlight. This height-adjustable, 34-inch, 5K 21:9 screen isn't just gorgeous; it's also bright with 500 nits of brightness and 98% coverage of the DCI-P3 gamut, which makes it ideal for video editors that work in that color space.
Don't like upgrading to a new computer every couple of years? It's also expandable up to 4TB M.2 storage and 128GB DDR4 RAM so there's room to grow here.

The best office all-in-one computer
For anyone looking for a simple work machine at a sensible price, the Dell Inspiron 24 All-in-One is the way to go. It's hardly the most powerful AIO on this list, but the 13th-gen Intel CPU makes it a powerhouse for multitasking productivity workloads, and the competitive pricing means you get plenty of bang for your buck.
Now, you shouldn't be expecting to play anything beyond the least graphically intensive games on this PC, but for general office work it excels with no slowdown or stuttering. A clean, lightweight design and super-easy setup process make it a good pick for anyone who isn't overly tech-savvy, too.
The port selection is generally good (although we would've liked to see more than one USB-C port) and the integrated webcam slides into the screen bezel when not in use, a nice little aesthetic flourish that also doubles as a privacy shutter. Lastly, the 1080p display is also a touchscreen, making quickly navigating your desktop a breeze.

The best all-in-one computer: FAQs
What is the best all-in-one computer?
The best all-in-one computer right now is Apple's iMac (24-inch, 2021). Although it's a little older, having been released in 2021, it's still the best in terms of design, performance, and value in our opinion.
It boasts that sleek and thin design, powerful performance that's quiet and robust enough for the more demanding creative tasks, and a price that is fairly affordable considering that it is an Apple product.
We're in the process of testing newer releases, however, so who knows? There might be a Windows all-in-one impressive enough to knock it off the first place.
What are the disadvantages of all-in-one computers?
The only potential downside of an all-in-one PC is it’s difficult to upgrade internal hardware. This means that if you like upgrading your tech on your own, you will have a slight disadvantage with an all-in-one computer. That's especially if you have something like an iMac.
How to choose the best all-in-one computer for you
All-in-one PCs, like their desktop and mobile counterparts, come in different configurations, designs, and price tags. Choosing the best one for you, therefore, is much like when choosing a laptop or a desktop PC. You must consider things like power and performance, as well as design and features.
Of course, since an all-in-one comes with its own set of peripherals, these are obvious considerations as well. Check the display, and make sure that it has the right size, resolution, color coverage, color accuracy, and brightness for your workload. Ensure also that the speakers sound great. Since many AIO PCs come with their own keyboard and mouse, make sure that those are comfortable to use and reliable. Otherwise, you'll only end up spending more to get better quality peripherals.
Since there are all-in-one PCs sitting at different price brackets, the price is a very important factor. Don't get an expensive one if you aren't going to take full advantage of its features, and don't get a cheap one when it can't meet your demands.
How we test all-in-one computers
Here at TechRadar, we believe in rigorously testing every piece of hardware that passes through our hands. If it fails to impress during testing, we won't recommend you buy any product that falls short of the performance median for its price range.
Our testing process varies from product to product. Specifically with all-in-one PCs, because they come with their own display and speakers, we test those on top of their ability to tackle workloads. We're always sure to run the most appropriate tests, including running editing benchmarks for an AIO designed for content creation. We also always examine its build quality and features to see how they measure up.
Finally, we take everything to see whether it aligns with the attached price tag. If you want to know more about how we test and rate the computers in this guide, check out our explainer on how we test laptops and desktops to learn more.
