Declutter your space while saving money with one of the best all-in-one PCs. These desktop computers pack their internals behind their displays, and they’re ideals for users who crave a more minimalist setup or with no patience to deal with a plethora of cables. 

But, don’t take that to mean that the best all-in-one PCs are less powerful. These minimalist solutions still rock plenty enough power to rival some of the best PCs out there. And, they're money-saving as well. Since they already come with a great display, you won’t have to shell one more money for one. Some even come with a keyboard and a mouse at no added cost.

Don’t compromise on performance and cost just to get a minimalist setup. The best all-in-one PCs, led by the Surface Studio 2 and iMac Pro, are the perfect and most cost-effective solutions. Here are our top picks.

1. iMac (27-inch, 2020)

A formidable AIO

CPU: 10th-generation Intel Core i5 – i9
Graphics: AMD Radeon Pro 5300 - Radeon Pro 5700 XT
RAM: 8GB – 128GB 2666MHz DDR4
Storage: 256GB – 8TB SSD
Display: 27-inch (diagonal) 5120 x 2880 Retina 5K display
Reasons to buy
+Improved internals+Can be configured to be very powerful
Reasons to avoid
-Design is getting old-Just two Thunderbolt ports

Even though the iMac 27-inch’s last update was only last year, Apple couldn’t help but step up in the upgrades department with its follow-up. Specs-wise, this model sports some massive improvements while also upgrading its webcam and microphones for a felicitous update. More people are working from home these days, and this seems like the best all-in-one PC to invest in without being forced to make some considerable space in your existing area. Sure, its overall design hasn’t seen so much as a tweak, making it look a bit tired, but if power is at the top of your list, this one’s an ace.

Surface Studio 2

2. Surface Studio 2

The best all-in-one computer for artists

CPU: Intel Core i7
Graphics: Nvidia GeForce GTX 1060 - GTX 1070
RAM: 16GB – 32GB
Storage: 1TB - 2TB SSD
Display: 28-inch 4,500 x 3,000 PixelSense display
Reasons to buy
+Powerful+Nothing like it
Reasons to avoid
-Very expensive

Back when the original Surface Studio hit the streets, it was a game changer for artists and content creators alike. And, even in 2019, the sequel still stands in a league of its own. The Surface Studio 2 doesn’t just feature the same gorgeous display and unique functionality, but it also ups the power significantly, making it a much more future-proof device. It’s still extraordinarily expensive, but if your use case is right for the Surface Studio 2, then, it’s hard to think of a better all-in-one PC.

iMac Pro

3. iMac Pro

The best all-in-one computer from Apple

CPU: 10-18 core Intel Xeon W
Graphics: AMD Radeon Pro Vega 56 - Vega 64
RAM: 32GB - 128GB
Storage: 1TB - 4TB SSD
Display: 27-inch 5K (5,120 x 2,880) Retina display
Reasons to buy
+Extraordinarily powerful+Beautiful Retina display
Reasons to avoid
-Very expensive

The iMac Pro, more than any other computer on this list, is aimed squarely at professionals – and it has the hardware to back it up. Packed with up to an 18-core Intel Xeon processor and up to 128GB of RAM, there isn’t a single thing you could throw at the iMac Pro to slow it down. And, while it is, without a doubt, outrageously expensive – it doesn’t really matter. If you’re the type of person that needs this level of power (you know who you are) then the price is absolutely justified.

Dell XPS 27 AIO

4. Dell XPS 27 AIO

A well-rounded jab at Apple’s ageing iMac

CPU: Intel Core i5 – Core i7
Graphics: Intel HD Graphics 630; AMD Radeon RX 570
RAM: 8GB – 32GB
Storage: 1TB HDD – 2TB SSHD; 512GB SSD
Display: 27-inch 4K (3,840 x 2,160) display
Reasons to buy
+Handsome display+Virtually unparalleled built-in sound
Reasons to avoid
-Relatively expensive-No HDMI in

The Dell XPS 27 AIO comes with this amazing articulating stand, and it comprises a mix of a massive 4K UHD resolution touchscreen with six ear-numbing speakers. Not only is it an attractive design, but it’s also top notch when it comes to power. Whether you’re making your own beats or listening to someone else’s, watching movies or editing your own, the Dell XPS 27 AIO is easily one of the best all-in-one PCs, and should be at the top of your list when shopping for a new PC.

HP Envy Curved All-in-One

5. HP Envy Curved All-in-One

A spectacle in everyway

CPU: Intel Core i5 - Core i7
Graphics: Nvidia GTX 950M - AMD Radeon RX 460
RAM: 8GB - 16GB
Storage: 1TB SSHD, 1TB - 2TB HDD; 256GB SSD
Display: 34-inch WQHD (3,440 x 1,440)
Reasons to buy
+Enveloping ultra-wide display+Full-bodied audio+Privacy-minded pop-up web camera
Reasons to avoid
-Exceptionally bulky

Not to be shown up by the 5K iMac or new Dell XPS AIO, HP has its own unique take on the all-in-one desktop. Though it also has all its components stored in its base like the Surface Studio, the HP Envy Curved All-in-One also adds in a booming speaker bar. Add in the ultra-wide curved screen and this is one of the best and most immersive PC for enjoying movies.

iMac (27-inch, 2019)

6. iMac (27-inch, 2019)

Everyone’s favorite all-in-one

CPU: Intel Core i5 - Core i9

RAM: 8GB - 64GB
Storage: 2TB SSHD - 2TB SSD

Reasons to buy
+Beautiful screen+Plenty of power
Reasons to avoid

We went all of 2018 without a new iMac, but the wait was worth it. And, while the 2019 iMac looks exactly like the 2017 model, it’s what’s inside that counts. Apple’s all-in-one PC was refreshed with all new components, including 9th-generation Intel desktop processors, Radeon Pro graphics and faster SSDs. And, because that luxurious 5K Retina display is still there, it’s a no brainer for all the Apple fans out there. Plus, there’s the fact that because the iMac (27-inch, 2019) is no longer the latest model, so it should be getting some tempting price cuts.

Lenovo Yoga A940

7. Lenovo Yoga A940

An iMac alternative

CPU: 8th-generation Intel Core i7-8700
Graphics: AMD Radeon RX 560 4 GB
RAM: 32 GB DDR4 2666 MHz
Storage: 1 TB 5400 RPM + 256 GB PCIe SSD
Display: 27" 4K UHD (3840 x 2160) IPS Multi-touch
Reasons to buy
+Good price+Stylus included
Reasons to avoid
-Older components-Screen not great in direct light

Lenovo’s latest all-in-one offering isn’t as powerful as Apple’s premium AIO, the iMac Pro, or even the recently updated iMac, which now offers a 9th-generation Intel Core configuration. After all, the 8th-generation chips and Radeon RX 560 graphics are aging at this point. However, it is still plenty powerful to meet the needs of creative professionals out there who are not entirely impressed by Apple’s pricey machines. On top of that, the Lenovo Yoga A940 has a few aces up its sleeves, including 100% Adobe RGB support and Dolby Vision, a set of Dolby Atmos speakers, a port offering that’s more generous than Apple’s all-in-one, and a stylus included in the box.
