Compact PCs are now no longer tied to the niche category as they are making quite a buzz in the mainstream consumer market. This mainly has got to do with the fact that CPUs, motherboards, and computer hardware components have shrunk in size while offering the same or a higher level of performance.   

There are now way more options in the compact gaming PC realm than ever before. What’s more interesting to know is you get the flexibility to explore and choose between different levels of compactness. 

You may be planning to move on from your current standard ATX gaming PC and switch to a slightly compact alternative. Or you may want the most compact PC as a side project. Whatever your requirements, we have got you covered by categorizing form factor compactness of compact PCs into three levels: 

Three levels of compactness of gaming PC form factor

Best mini gaming PCs aren’t all the same, both in terms of overall form factor size as well as performance. As such, clubbing them under one single category can make it confusing for you to get your hands on the right type of model size.

Here are three types of mini gaming PCs that differ in terms of overall size, performance, and customizability/upgradability: 

1. Small Form Factor (SFF) PCsmost compact 

SFF PCs are the most compact in the bunch. Also known as mini PCs, SFF PCs are highly compact and are about the similar size to gaming consoles; some models are even smaller. Unlike standard tower PCs, SFF PCs have a vertical layout (similar to WiFi routers). 

Most modern high-performance SSF PCs come with soldered hardware components, including a soldered-on CPU. Both Intel and AMD have their own take on developing motherboards/SoCs (system on a chip) specifically for mini/SFF PCs. 

Intel NUC (Next Unit of Computing)

Intel develops a specific line of motherboards called NUC boards for SFF PCs. These motherboards have soldered-on Intel core processors of various generations. Similar to ATX motherboards, NUC boards have several M.2 and PCIe expansion slots.

AMD Ryzen Embedded Processors (SoCs)

In Intel’s move to capitalize on the increasing popularity of mini PCs by developing mini CPU-soldered boards, AMD has followed suit. The CPU manufacturer has a dedicated line-up of Ryzen-embedded SoCs that are specifically designed for mini gaming and non-gaming PCs.

Do note that there is not just one but several types of mini PCs that use these Intel and AMD CPU-soldered motherboards. 

2. Mini ITX PCs – second-most compact 

Mini ITX PCs are slightly larger than mini SFF PCs in terms of overall dimensions. They use the industry-standard mini ITX motherboards that have standard sockets for removable/upgradable Intel and AMD CPUs.

3. Micro ATX PCs – third-most compact

Micro ATX PCs are slightly larger than mini ITX PCs. They are compact enough to be smaller than standard ATX PCs and large enough to house industry-standard micro-ATX motherboards. Micro ATX PCs offer the best upgradability options as the tower case includes more room for additional peripherals.

Mini PC vs Mini ITX vs Micro ATX 

Here’s a brief comparison between these three compact PC types to further help you gauge the pros and cons of prioritizing a compact form factor over performance and vice versa. 

Best Mini gaming PC – SFF models

Mini gaming PCs with CPU-soldered motherboards are in a league of their own. They are highly compact to the point that you can take one along with you for LAN gaming parties and gaming competitions. They also work great in freeing up a ton of desktop space and help you declutter your gaming space. 

And if you are someone who prefers to keep power consumption in check, mini gaming PCs are a perfect alternative to standard ATX PCs for you. Here are 4 best mini gaming PCs that differ in terms of CPU brand, overall hardware configuration, price, and upgradability:
