Buying the Smallest ATX Case: Points to Remember

This exclusive guide is for you if you are just beginning to assemble your first, second……….. 100th gaming PC.

Talking about ATX, you have to choose between ATX, Micro ATX, and Mini-ITX.

You have three different versions due to the motherboard size categories.

ATX is the largest, followed by micro ATX, which is a bit small, and the mini-ITX being the smallest in size.

So, for better understanding, the ATX case is compatible with both micro ATX and mini ITX because both of them have smaller motherboards so they would easily fit inside the ATX.

Here are the specifications:

ATX Motherboard size: 12 × 9.6 inches (305 × 244 mm)

Micro ATX Motherboard size: 9.6 × 9.6 inches (244 × 244 mm).

Mini-ITX Motherboard size: 6.7 × 6.7 inches (170 x 170 mm)

Points to Remember:

1. The ATX case should be durable and strong. We suggest you avoid buying cases that have plastic built, including the ones which do not come with tempered glass. Overall, the whole idea of buying an ATX is that it prevents your inside system, so it needs to be strong and durable.

2. Do not fall for an astounding design. The ATX should also support a proper airflow system. You would not want your PC to overheat and die in the midst of playing your favorite game.

3. Wire management also plays an important role. The case that you intend to buy should have a proper mechanism for wire management.

4. Design and LED lights would be cherry on top. However, do not eventually fall for it without considering the above points.

Frequently Asked Questions (FAQ)

  1. What is the smallest computer case?

    The Thermaltake Core G3 is the smallest computer case on our list. It is small, compact in size, but offers great performance mainly due to its outstanding cable management and dedicated slots for other PC components.

  2. Can ATX fit a micro ATX case?

    Absolutely! The ATX cases are specifically designed keeping in mind that they are “backward compatible” with micro ATX motherboards. The standoff locations used by the Micro ATX motherboards are the same as that of ATX. With that concept, a micro ATX motherboard can easily fit inside an ATX case, but the opposite is not possible.

    If you are looking for a compact Mid Tower case, you can go for NZXT H510 (affordable case), or Corsair Crystal 460X or the Corsair Carbide 400C compact case.
