The best all-in-one computers of 2025: Expert tested and reviewed

1 day ago 2

All-in-one (AIO) computers combine performance and speed in a space-saving design, integrating components into a single monitor. By eliminating the need for a desktop tower, desk clutter is greatly reduced. These machines are ideal for households wanting a clean setup without sacrificing basic functionality. However, AIO computers typically offer less hardware than traditional computers. These devices have limited upgrade options and reduced repairability, so choosing the right one up front is key.

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

We tested several AIOs across various budgets and use cases. Our top pick is Apple's 24-inch M4 iMac, which we praise for its strong performance, sharp display, and sleek design. Still, there are plenty of good alternatives, including Windows models, that are perfect for certain needs. Check out the following for our recommendations to help you find the best AIO computer for your space and workflow.

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 iteration takes everything everything that we loved about 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. The hardware enhances workflows, enabling faster processing and rendering speeds for certain tasks, like 4K video editing. AI models demand the right supporting hardware, so the base model includes 16GB of RAM.

Older models settled for 8GB. This upgrade improves the iMac's ability to multitask. The iMac isn't a gaming machine by any stretch; however, the 10-core GPU does support ray tracing and dynamic caching, which allows for a decent gaming experience.

It also 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.

And the best part is that all this costs $1,299.

The HP OmniStudio X is a well-rounded all-in-one desktop. At $1,799, I wouldn't call it cheap, but it earns its price in various ways.

First off, the computer houses a 32-inch 4K IPS display. It's no exaggeration when I say that the screen is the OmniStudio X's standout feature - bright, colorful, and sure to turn heads in the office (or at home). I should point out that it only has a refresh rate of 60Hz. While it's not meant for high-end gaming, the screen provides a good workspace for creative tasks and enables immersive movie watching.

Review: HP OmniStudio X 31.5

Alongside the display is a set of powerful hardware. This model boasts an Intel Core Ultra 7 Processor, a 1TB SSD, 32GB of RAM, and a dedicated Nvidia RTX 4050 graphics card. A configuration like this is more commonly seen on powerful gaming laptops, but here, we have it on an office machine.

A device like this is well-suited for content creators or video editors. It has enough muscle to power through demanding productivity tasks. Storage and memory are generous out of the box, with plenty of headroom for large files or multiple users. Needless to say, it runs like a premium desktop but without all the messy cables.

No, you're not seeing double. HP makes some of the best AIOs on the market, so it only makes sense to include another on this list. This OmniStudio X model has several differences from the previous entry - most notably is its size. The screen is significantly smaller, measuring 27 inches diagonally, outputting at 2K resolution.

Don't misunderstand: 2,560 x 1,920 is still high quality, delivering vibrant colors and detailed imagery. When combined with the dual 5W speakers, HP's monitor delivers an immersive experience few other AIOs are capable of delivering. I should also mention the company offers variants equipped with touchscreens 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 that it comes with Intel AI Boost. As the name suggests, it's software that enhances the AIO's performance via artificial intelligence. It's part of a recent effort by tech manufacturers harnessing the power of AI to improve user experience and not just limit them to rarely used features. Few AiO computers have this capability, and the OmniStudio X is one of them.

Buying an AIO computer can be expensive, 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, etc. 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 be aware 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.

Asus' A3402 All-in-One PC is a small AIO with impressive specs for its low cost. It features a 24-inch Full HD touchscreen covered in an anti-glare coating to ensure visibility even in brightly lit environments. The developer gave its model thin bezels around the glass, making the screen appear bigger than it actually is. I've always been a big fan of companies maximizing monitor real estate. It allows people to get the most out of their purchases.

Also: I recommend this Asus laptop to creative professionals and business users alike. Here's why

Above the screen is a 720p webcam. 720p is pretty low for a camera, leading to fuzzy-looking video calls. The Asus AIO makes up for its low-quality camera by delivering a shockingly powerful audio system. It houses a set of powerful speakers enhanced by both Dolby Atmos and SonicMaster to output immersive sound. AI Noise-Canceling Technology supports the built-in array microphones to block out outside noise from leaking through. That way, the only thing your audience hears in a video call is you.

The model comes with an Intel Core i5-1235U processor, an integrated Intel graphics card, plus 8GB of RAM. A configuration like this won't be winning any awards, but it's good enough to handle a full day's work.

When searching for the best AIO computer for creative users, I felt compelled to revisit an old favorite: the M3 iMac. It was once our pick for the best AIO ever, and to this day, it remains a top choice. So, you're probably wondering: "What is so good about the older iMac that it had to make a return?"

Well, Apple's M3 chip is still top-notch hardware. The processing unit, which consists of four performance and four efficiency cores, is great at tackling heavy workflows like digital illustration, music production, and some light video work. Additionally, the unified memory allows the chipset's CPU, GPU, and Neural Engine to work together smoothly.

Another big reason I'm so bullish toward the M3 iMac is the mode's stunning 24-inch 4.5K Retina display. It supports over a billion colors and offers exceptional clarity and color accuracy.

The M4 iMac is the better version; however, the M3 model has it beat in one important area: cost. At the time of this writing, the M3 iMac is on sale for $1,000 at Best Buy, although refurbished units can be found for even cheaper.

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, we strongly recommend the 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. It also supports Dolby Atmos audio. In our review of the Yoga AIO 9i, we noted that its 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 becomes apparent that this is a powerful combination. It can run multiple apps and browser windows open while playing videos simultaneously and not slowing 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, a hard-to-reach place.

On the surface, the Acer Aspire C27 may look like a regular old computer monitor, but don't be fooled -- it is a very 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 and weighing slightly over 16 pounds.

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. Additionally, 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, blocking your view.

At the top is a 5MP "Super" HD webcam supported by Acer PurifiedView, which ensures clear video calls. Plus, a pair of stereo microphones for clear audio. Acer EyeSense also powers 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 really limited.

What are the tariffs in the US?

The recent US tariffs on imports from countries like China, Vietnam, and India aim to boost domestic manufacturing but are likely to drive up prices on consumer electronics. Products like smartphones, laptops, and TVs may become more expensive as companies rethink global supply chains and weigh the cost of shifting production.

Also: Tariff war has tech buyers wondering what's next. Here's what we know

Laptops and PCs are also hit hard by the new U.S. tariffs, with import duties potentially increasing prices by up to 35%. Many major brands still rely on Chinese and Vietnamese factories for assembly, meaning consumers could soon pay significantly more for everything from budget Chromebooks to high-end gaming rigs.

These tariffs may accelerate efforts to move production to regions like Mexico or India, but shoppers can expect higher costs and fewer discounts in the short term.

Right now, it looks like some tech may be exempt from the issued tariffs, but since it's always changing and developing, we are keeping an eye on it and will update you on the latest.

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.
