All-in-one (AIO) computers can do it all without sacrificing valuable desk space. These often-stylish systems build the processor, storage, and other components directly into the display. You don't need a separate desktop tower, and you have fewer cables cluttering up your work area. AIO computers are convenient but have a few drawbacks compared to traditional desktop PCs.

These systems often have less powerful components, few (or no) upgrade options, and reduced repairability. For this reason, it's important that you buy the right AIO computer from the getgo. A device like this is a great fit for households looking for a space-efficient device with a decent hardware and won't miss a laptop's portability. But the most important here is: which one should you buy?

What is the best all-in-one computer you can buy right now?

We went hands-on with several all-in-one computers across various categories, covering different price points, use cases, and operating systems. Our top pick is Apple's 24-inch M4 iMac It was chosen for its strong performance, high-resolution display, and eye-catching design. Of course, the iMac is not the only option out there, and we found plenty of appealing Windows-based choices for different needs. Read on for the rest of our picks to help you find the best AIO computer for you.

The best all-in-one computers of 2025

Taking the top spot on this list should come as no surprise -- it is the 2024 iteration of the Apple iMac. This year's iteration takes everything fantastic of the previous generation and improves upon it.

The 2024 iMac is a versatile AiO powered by the company's M4 chipset, which outperforms the older M3 processor by a good amount. Thanks to artificial intelligence, workflows are enhanced enabling faster speeds for work productivity and creative tasks such as 4K video editing. AI software demands the right supporting hardware so the base model now includes 16GB of RAM, improving the iMac's multitasking capabilities. The best part is maintains its $1,299 price tag.

The iMac still shouldn't be considered a gaming machine by any stretch; however, the 10-core GPU does support ray tracing and dynamic caching. These pieces of software allow for a decent gaming experience.

It houses a 24-inch, 4.5K resolution Retina display for sharp and vivid imagery. What's neat about the computer is it can output to another screen at 8K resolution or to a dual-monitor setup at 6K resolution each. Other notable features include a 12MP webcam that comes with Center Stage for automatic framing, support for the USB-C standard, and a thin design available in a wide array of colors.

HP is in a unique position among AIO manufacturers possessing huge presence in the market. The company makes a lot of great AIO computers to the point where you could arguably fill out this entire list with HP models. However, we decided to slim things down to one of its best offerings: the Envy 34.

This thing is a beast, measuring 34 inches diagonally and making one of, if not the, largest AIO machine out there. Most of these devices peak at 27 inches, yet HP pushed the limits. With this model, you receive an outrageous 5K (5,120 x 2,160) WUHD display. It supports nearly the entirety of the DCI-P3 color gamut, enabling eye-catching colors. Plus, it has a maximum brightness level of 500 nits. HP even covered the glass with an anti-reflection coating so you can continue seeing the screen even if the sun is peeking through the blinds.

Also: Thanks to Nvidia, there's a new generation of PCs coming, and they'll be running Linux

For 2024, the company slimmed down its offerings by only having a single Envy 34 configuration on sale. Don't worry, though; it's still plenty powerful. The computer has a 12th-Gen Intel Core i9-12900K processor, an Nvidia GeForce RTX 3050 graphics card, and a whopping 128GB of DDR5 RAM. This configuration ensures optimal performance, especially when multitasking or rendering high-resolution videos. And your projects will be saved on the huge 16TB SSD.

Purchasing the HP Envy 34 also includes a free mouse and keyboard as well as a 16MP True Vision binning IR privacy camera.

Alongside the Envy 34 is the OmniStudio X as the second HP pick on this list. You can look at this model as a toned-down version of the previous entry. It's not as large, nor does it have the ultra-high resolution display, but the device is still quite impressive. For example, it features a 4K display instead of 5K, which, combined with the dual 5W speakers, delivers an immersive experience few other AiOs can hope to offer. I should mention that HP offers touchscreen versions of the OmniStudio X for people who enjoy the extra level of interactivity.

Inside its chassis is an Intel Core Ultra 7 155H CPU. What's unique about this processor is it comes with Intel AI Boost. It's a piece of software that, as the name suggests, enhances the AiO's performance via artificial intelligence. It's part of a new wave of hardware that harnesses AI. Few AiO computers have this capability, and the OmniStudio X is one of them.

Other notable features include Wi-Fi 7 and Bluetooth 5.4 support, which enable fast wireless connectivity. It also has a 5MP webcam as well as two 5W speakers fine-tuned by the company's PolyStudio brand, delivering booming audio.

Buying an AIO computer can be an expensive endeavor, but it doesn't have to be -- as this Dell Inspiron 24 5420 shows. This Dell is one of the many AIOs out there that strikes a good balance of performance and cost.

Inexpensive models tend to cut corners by opting for smaller screen sizes, old hardware, and such. But not so with the Inspiron 24 5420. As its name suggests, it sports a 24-inch InfinityEdge display with 1,920 x 1080 pixels and a 60Hz refresh rate. The device sports an InfinityEdge screen is Dell's term for its thin bezel design. The display also has an anti-glare coating, ensuring the picture remains crystal clear even in bright environments.

Inside, the Inspiron 5420 comes with a solid hardware configuration. The mid-range configuration listed here has a 13th-Gen Intel Core i5-1335U processor, an integrated Intel UHD graphics card, 8GB of memory, and 512GB of storage. You can adjust some of the components (which scales the price up or down accordingly), but remember that some upgrades are tied to one another. For example, step up to a beefier build with a 1TB SSD, and you also need to upgrade the graphics to an NVIDIA GeForce MX550 GPU, the processor to an Intel Core i7-1355U, and the RAM to 16GB.

One quirk worth noting: This AIO only comes with a single USB-C port. Which is strange to see because the Inspiron 5420 has a wide array of ports, including HDMI, RJ45, and USB-A. It would've been nice to have at least one more.

The Lenovo IdeaCentre AiO is a small AIO with impressive specs for its low cost. It sports a 24-inch Full HD display that supports 99% of the RGB color space and runs at a refresh rate of 100Hz. (I've seen way more expensive monitors with a much lower refresh rate than this.) Faster speeds allow for smoother on-screen motion, and this model has some of the best models beat. Additionally, the glass is covered in anti-glare to maintain clarity under brightly lit conditions, especially since it has a peak brightness of 250 nits, which isn't very high.

Lenovo's machine houses an Intel U300, an integrated Intel UHD graphics card, and 8GB of RAM. A configuration like this won't be winning any awards, but it is good enough to handle a full day's work. If you prefer something more powerful, the company also has a version of the IdeaCentre AiO with a 13th-Gen Intel Core i5-13420H CPU, 16GB RAM, plus a 512GB SSD. It's not a bad upgrade, although keep in mind that the display remains the same.

The inclusion of the Surface Studio 2+ here may seem strange to some. It runs on an old 11th-Gen Intel Core i7 processor instead of the recent 12th-Gen chip. And the bezels around the screen are pretty thick, robbing the display of its potential size. But Microsoft's computer has a lot of things going for it that still earn it a spot on this list. Chief among them is its Zero Gravity Hinge, which allows you to position the screen at an angle. Being able to adjust the screen in this manner is great for creative professionals who need to draw, but don't have a tablet. You can instead illustrate directly on the touchscreen.

Speaking of which, the touchscreen on the Surface Studio is fantastic. It has an image resolution of 4,500 x 3,000 pixels, which is better than 4K. This level of quality is further enhanced by its support for the DCI-P3 color gamut and Dolby Vision. What's more, it has a 1200:1 contrast ratio. Putting everything together results in a display capable of showing vibrant colors in stunning quality.

Review: Microsoft Surface Studio 2+

Going back to the hardware, the computer punches above its weight class thanks to its Nvidia GeForce RTX 3060 graphic card. It gives professionals a powerful GPU to render 3D objects. Plus, the 3060 model is quite good at meeting the performance requirements for video editing. That type of work can be tough on other AIOs, but the Surface Studio 2+ handles them with ease. Other notable features include 1TB, 32GB of RAM, three USB-C ports, and a 1080p webcam.

Microsoft Surface Studio 2+ specs: OS: Windows 11 Pro | CPU: Intel Core i7-11370H | GPU: GeForce RTX 3060 Laptop GPU, GeForce RTX 3060 Laptop GPU (6GB) | RAM: 32GB (DDR4) | Storage: 1TB SSD | Camera: 1080p + IR for Windows Hello face authentication | Audio: stereo 2.1 speakers with Dolby Atmos, dual far-field studio mics, 3.5mm headphone jack | Dimensions: Base: 9.8 x 8.7 x 1.2 inches • Display: 25.1 x 17.3 x 0.5 inches | Weight: 21 lbs

After a long day's work, nothing beats kicking up your feet and watching a movie. If you're looking for an AIO computer to double as an entertainment center, then we strongly recommend the Lenovo Yoga AIO 9i from Lenovo. It has a huge 32-inch Ultra HD 4K (3,840 x 2,160 pixels) display, making it perfect for viewing movies or editing 4K videos. The screen produces vibrant colors and crisp detail.

This model has a Harmon Kardon-certified audio system comprising two tweeters and two woofers. And it supports Dolby Atmos audio. In our review of the Yoga AIO 9i, we noted how this AIO's speakers output immersive audio with deep bass and powerful treble.

Review: Lenovo Yoga AIO 9i

The Yoga AIO 9i comes with a 13th-Gen Intel Core i9-13000H processor, 16GB of memory, and a 512GB SSD (if you're lucky, you can catch the on Amazon for less). When using this hardware for everyday work, it quickly becomes apparent that this is a powerful combination. It's capable of having multiple apps and browser windows open while playing videos at the same time and not slow down once.

As much as we like this computer, it's not perfect. It looks attractive, with a metal bar connecting the screen to the base. However, it also has some awkward design elements. The ports are on the back of the base, which is a hard-to-reach place. Regardless of hiccups like that, this is still a great machine.

On the surface, the Acer Aspire C27 may look like a regular old computer monitor, but don't be fooled—it is pretty capable AiO. This display is a good choice if desk economy is a big concern. It's a slim device measuring about 1.5 inches thick as well as weighing a little over 16 pounds. The screen is easy to set up and, most importantly, won't take up much space.

It runs on a 12th-Gen Intel Core i5-12450H, integrated Intel UHD graphics card, 16GB DDR5 RAM, and a 1TB SSD. These are top-notch specs for a work machine like the Aspire A27. What's more, the 27-inch display has a screen-to-body ratio of 90.71%. That means most of what you see will just be the screen. The frame won't be encroaching on the area.

At the top is a 5MP "Super" HD webcam supported by Acer PurifiedView, ensuring clear video calls, plus a pair of stereo microphones for clear audio. Acer EyeSense is present as well to power certain "smart features" like auto-dimming. Users can also enjoy high-speed wireless connections via Wi-Fi 6E.

Acer offers smaller configurations of the Aspire C27. There's a 24-inch and even a 21.5-inch model if desk space is in short supply.

Before buying an all-in-one computer, pay attention to the follow factors.

Design: Consider the size of an AIO computer, camera and speaker placement, location of ports, and its overall aesthetics. If you're going to spend money on something, it should at least look good. Performance: AIO computers, as a whole, don't have the best performance as they're meant to be easy-to-use, lightweight machines and often lack dedicated graphics processors. Still, keep an eye out for models that balance hosting hardware and affordability.Display: Obviously, it's important to want and have an AIO computer with a great-looking screen since you'll be staring at one for hours. But also consider unique capabilities like touchscreen functionality.Features: Lastly, consider the AIO's full range of features, including its port options (does it have USB 4?) or display capabilities.

At ZDNET, we occasionally receive AIO computers for reviews. We use the model for a while, running it through benchmark tests and seeing firsthand where it excels and where it stumbles. Information from personal usage is taken into account as well.

Once we've compiled a list, we separate the best of the best using the guidelines noted in the previous entry. We also consider the components the AIO has, available upgrades, how well it performs, the display's size and type, and any additional features and ports. Of course, there are certain factors we ignore. No point in taking portability into account when they commonly weigh over 20 pounds.

Check ZDNET's in-depth process in how we test laptops and computers.

According to Lenovo, the average lifespan of an AIO computer is about five to eight years, but it depends on a variety of factors. It depends on how often you use it, if you take good care of the machine, and if you frequently install updates. It also depends on whether your needs change over time, and you need more powerful components the AIO lacks.

Repairability is, by far, the biggest drawback to all-in-one computers. According to ZDNET's computer expert June Wan, "the internal parts are typically weaved into the chassis so that there's little room for modification." This is done to save as much space as possible. Additionally, this leads to a short life span. After about four to eight years, you may begin to experience performance problems and you'll have to bring the entire system to a professional technician to fix it -- if they can.

Another drawback is the lack of upgradability. That means you're out of luck if a year after you've bought the machine you want more memory or a larger SSD.

Of course, there's also the price point to consider. AIO computers are typically more expensive than traditional desktop computers.

It all depends on your priorities. If you value having as few cables as possible, a degree of transportability, and space-saving and stylish design, AIOs are definitely for you. On the other hand, if powerful performance, upgradability, and repairability are what you're after, then a traditional desktop PC will generally offer more for your money.

AIO computers are ideal for users in confined spaces. The compact nature of the machines makes them perfect for receptionist desks, dorms, medical centers, and other settings that need desk space for other things.
