Guide to Buying the Best Smallest ATX Cases
You need to be aware of a few things before you purchase your ATX case. You will need to consider those things as failure to do so will result in the purchase of a model that will not be compatible with your system. To avoid such a mishap, let us look at a few attributes of the ATX cases.
A form factor is basically the size of your motherboard in terms of ATX. Usually, depending on how large your motherboard is, you can either fit EATX, ATX, microATX, or Mini-ITX with your gaming setup. The Mini-ITX is the smallest, while the EATX is the largest.
In fact, there are no standard dimensions for PC cases. Instead, their form factor will be decided by the manufacturers based on the size of the motherboard that will be installed in it. They can be classified into three categories: Full-Tower, Mid-Tower and Mini-Tower. However, they might go by various names. For instance, Corsair refers to PC cases that support the microATX motherboard as “Small Form”, but Thermaltake refers to them as “Micro Case”.
Therefore, you shouldn’t concern too much on the name of PC case form factor. Instead, you should be aware of the type of motherboards they support and the amount of room for other important parts like graphics cards, power supplies, etc.
Smaller cases have lesser features. However, they can leave behind much room for other stuff. If you are looking for features, then microATX isn’t probably the best choice. The Mid-Tower or larger case may be the right choice for you.
