Computers have been steadily shrinking for decades. And because of this, it’s possible to get a high-end computer with some serious performance in a small form factor.
Perhaps the most optimal balance between size and performance is the mini ITX form factor. Mini ITX motherboards are smaller than other standard motherboard form factors, while still allowing you to use standard PC parts.
That means that if you’re looking to get a small computer that’s big on performance, you’ll want a mini ITX PC. You can always build one yourself to get the best performance-to-dollar ratio.

1. Thermaltake Reactor 380
Best prebuilt mini-ITX gaming PC
If you want a mini ITX PC that’s powerful and capable of handling just about anything you can throw at it, then you’ll want to check out the Thermaltake Reactor 380.
At the forefront of this top-tier build is the Ryzen 7 5800X and the NVIDIA RTX 3080. Coupled with the 16GB of RAM and a 1TB Seagate FireCuda 520 NVMe SSD, this PC is capable of handling any gaming, streaming, or other heavy workloads you can throw at it.
There to reign in the powerful hardware and keep things cool is an AIO liquid cooler. Mixed with the unique case and optimized airflow, the Thermaltake Reactor 380 does a great job of keeping the PC as cool as it looks.
No matter how you use it, whether you want to game, stream, or do work, if you want a small PC with a lot under the hood at a great price, this RTX 3080 desktop PC offers the best of everything.
2. CUK Stratos Mini Gaming PC
The best mini PC for streamers
Whether you’re an aspiring game streamer, or you just want a top-tier gaming PC, you’re going to need a PC with a strong processor and a good graphics card. And the CUK Stratos Mini Gaming PC fits the bill.
Much like the Thermaltake Reactor 380, this PC is a powerhouse packed into a small form factor computer. But with an RTX 3090 and a Core i9 12900F, this impressive little machine hits even harder, albeit at a higher cost. With it also comes a decent amount of space and more than enough RAM for gaming, streaming, rendering, and editing.
This PC definitely lives up to the steep price tag attached to it. If you just so happen to be looking for a small yet powerful PC, and can squeeze this into your budget, this prebuilt RTX 3090 desktop PC is an excellent choice.
3. Adamant Custom Workstation
A great option for serious work
We all love gaming computers. But as powerful as they can be, they’re not always the most suitable machine for professional use. With gaming-centric hardware driving up costs or requiring sacrifices elsewhere, a dedicated workstation makes more sense if, for example, you’re able to skimp on graphics if it means having more RAM and storage at a lower price.
That’s why if you’re looking for a great modern workstation, then you can’t go wrong with the Adamant Custom Mini ITX Workstation. Being one of the more affordable options on this list, it places an emphasis on professionalism with its sleek, modern look. Under the hood, it comes with Intel’s 10-gen flagship CPU, 32GB of DDR4 memory, and a combined total of 5TB of storage (1TB NVMe + 4TB HDD).
At a cheaper price than our number one pick, this is a great choice if you want a professional PC that can handle whatever work you plan to throw at it. Plus, you can always throw in a graphics card later, if you decide you want to do some gaming on the side.
4. ZOTAC MAGNUS ONE
Best prebuilt mini ITX HTPC
If you want a tiny PC that is more affordable and is still capable of gaming, then you might consider the ZOTAC MAGNUS ONE. This little PC is somewhere in between a mini ITX PC and a mini PC, featuring a custom H470 chipset motherboard. However, it does feature a swappable CPU, along with other components, making it a mini ITX PC in our book.
Semantics aside, this machine is the perfect size for your living room, and it’s got plenty of power to boot. With a 10th-gen Intel Core i5, an RTX 3060, 16GB of memory and 1.5TB of storage, it’s easily capable of doing some serious gaming. With this computer, you’ll be able to hit at least 60 FPS in most games at 1440p resolution.
So whether you’re looking to do some epic couch gaming, or you just want a small and sleek gaming PC on your desk, this no-frills mini PC is available at a great price.
5. Velztorm Natalix
Honorable Mention #1
If you want a mini ITX gaming PC that strikes a good balance between catering to professionals and to gamers, check out the Velztorm Natalix Mini ITX gaming PC. This computer is great as a light gaming PC, featuring mid-range hardware.
With its Ryzen 7 5800X and GTX 1660 Ti combo, this computer will easily play most triple-A titles at 1440p at around 60 FPS with no issues. But this computer isn’t solely for hardcore gamers. In fact, the 64GB of RAM and 2 TB of storage make it seem more like the Adamant workstation as a computer aimed at professional workloads, with the addition of a graphics card for a little gaming on the side.
This computer is a bit expensive for its capabilities. But if you want a sleek, gamer-esque computer that blends performance and aesthetic in a small mini ITX package, then this is a worthwhile consideration.
6. AVGPC Mini Gaming PC
Honorable mention #2
Having a sleek gaming PC is one thing. But trying to find a prebuilt mini ITX computer in white is pretty difficult. Fortunately, if you’re looking for one, we found the AVGPC Mini Gaming PC, which will look great in any minimalist home setup.
This modest minimalist build features a solid combination of hardware, with a Ryzen 7 5700G, an RTX 3060 Ti, 16GB of memory, and a 1TB NVMe SSD, all wrapped in a sleek white shell. With the hardware inside, you’ll be able to play just about anything you throw at it at a high frame rate, and for its price, it’s a solid deal.
If you’re looking to balance budget, performance, and aesthetic, and you just have to have a white PC to go with your home’s décor, then this is it. This is the computer you want.
Small Computers with Big Performance
Mini ITX computers are a great compromise between small mini PCs and more capable full-sized desktops. They allow you to choose a small case while still being able to use parts interchangeably with other computers, making them capable of packing a punch when it comes to gaming and professional use.
If you want the best bang for your buck, then it’s best if you build your own PC.
