Buying the Smallest ATX Case: Points to Remeber

This exclusive guide is for you if you are just beginning to assemble your first gaming PC.

Talking about the ATX, you have to choose between ATX, micro-ATX and mini-ITX.

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

The 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 Remeber

1. A great ATX case is 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 proper airflow system. You would not want your PC to overheat and die in 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.

Congratulations! You can now buy your compact and small ATX case.
