ATX is an evolution of the Baby-AT form factor, developed by Intel in the mid-90s. It’s a motherboard specification that PC enthusiasts and gamers spend their money on; it still needs protection though – cases can be full towers for standard ATX motherboards like Full-Tower Cases or Mid Towers with ample room to spare between components (like most systems do).

Mini ITX might seem small at first glance but this type also includes some larger microscale variants which usually come equipped with enough storage space inside them so they’re perfect if your computer will never grow too big!

ATX cases come in a variety of sizes and shapes. You can find one that is perfect for your computer aesthetic needs, at just the right price point too!

These little guys don’t skimp out on features – they’re got it all: from water-cooling radiator mounts to dust filters with plenty more space than their standard counterparts so you’ll never run into problems fitting everything inside these compact creations again (even if we do say so ourselves).

Buyer’s Guide for Best Smallest ATX Cases

Buyers guide for Best Smallest ATX Cases
Buyers guide for Best Smallest ATX Cases

Form Factors:

ATX cases come in a few different form factors. The two most common are mid-tower and full-tower cases. Mid-towers cases are smaller, less expensive, and allow for a mid-sized ATX motherboard.

Full towers have more room for components and they provide better airflow for your PC hardware, but they aren’t always necessary depending on the type of build you’re building out (how many hard drives/GPUs will you be using? What kind of processor do you plan to use?)

If the case is too small then there’s not enough space inside it to properly run cables or manage cords while if it’s too big then it means that you’re paying extra money for features that won’t help your components run as well they could.


When buying a case it’s important to be sure that there is plenty of airflow inside the tower and that each component has its own fan speed.

If you’re building out a high-end gaming PC then we suggest getting at least one extra case fan to help keep your components cool and running optimally for maximum performance.


Having USB ports on the front or top of your Tower can be extremely helpful, especially if you plan on using an external hard drive enclosure or flash drive with another computer.

However, cases with USBs throughout the front may disrupt airflow so make sure you account for this when purchasing your new system! (You want to make sure there’s room for all of your components to breathe).


Make sure you check what size motherboard your case supports before purchasing it. For example, if you have a mid-tower case that supports an ATX motherboard but only wants to use micro-ATX then you will need to find another case because the motherboards are not compatible!

If you’re looking for a smaller system it’s important to note that not every ATX Case will be able to support mATX motherboards, so make sure that whatever size you are needing or planning on getting is actually supported by the tower itself!

Case Build Quality:

It’s important to understand that the ATX case you buy is able to be used for building out your PC. Make sure that whatever one you are getting has enough space between where you put your components so you can actually plug in cables and wires!

If it’s too cramped inside then there will likely be issues with airflow, cord management, and proper installation of hardware pieces. If this is the case then it could cause component failure or just not perform as well as it should – all because of poor quality control!

Processor Compatibility:

Make sure that the tower supports the processor you will be using before buying it. An older generation motherboard might work perfectly fine with an AMD processor but could have compatibility problems with AM4+ motherboards.

GPU Compatibility:

If you’re planning on using multiple GPUs make sure that your tower can support the weight of it!

There are towers out there that only support up to four graphics cards (6 Pin not 8-Pin) but if you want to use 8+ then it’s best to find an ATX Case that has extra support by way of metal reinforcement or extra case fans which will help maintain airflow and heat management around the motherboard.

Cable Management:

Cable management is arguably the most important part of building out a PC. If you’re trying to save yourself some time then it’s best to find an ATX case that supports cable routing by way of grooves, channels, or designated spaces for moving your cables around quickly and easily.

That way you know exactly where every cable will go without having to guess (or risk cutting yourself on sharp edges!) It can also help reduce airflow problems if all of the cords are routed correctly.

Will Mini ATX fit the ATX case?

No, not all ATX cases are compatible with Mini ATX motherboards – make sure to read the dimensions of any case you are looking at carefully.

Will micro atx fit a regular size tower?

Yes, but only if the motherboard is backward compatible which most modern Micro ATX boards are. It’s important to remember that just because it fits doesn’t mean it will work properly too!

Make sure to do your research before buying if this is the case because compatibility issues can arise even between two boards that were both made by one company (such as Asus or Gigabyte.)

What size is mini ATX?

The smallest mini ATX motherboard is 9.6″ long x 8.2″ wide.

What size is micro atx?

The smallest Micro ATX motherboard is 11.6″ long x 10.4″ wide.

Can a full tower fit in a mid-tower case?

Yes, but it will be very tightly squeezed and won’t have any airflow space to work with – the best bet would be to go for a half-height PCI-E card or look into lower-profile cards that aren’t as thick/heavy if you can find them.

Most mid towers should support larger ATX motherboards by way of mounting holes, but always double-check just to make sure!


The Best Smallest ATX Cases are the ones that will fit your needs best! It’s important to understand what you need from a case before going shopping so you don’t find yourself buying something only to have it sit in your home unusable because it doesn’t fit your needs.
