Buying Guide

Components:

The components that you are going to use determines which case you buy. For example, if you need a simple operating PC with minimal component requirements, you can choose any of the smallest ATX cases listed here. But if you require a large number of components, make sure that the case has enough space to accommodate it all.

Expansion:

You should always consider that you will need additional components in the future, no matter how good your pc is right now. So, always look for the cases that have cases and additional drive bays and PCIe slots for expansion in the future.

Cooling System:

Check that the case has enough available mounts for the fan-based cooling system. Also, make sure that the case has a proper airflow channel or not. A case with support for liquid cooling would be the best for optimal thermal cooling.

Cable Management:

This is yet another feature that you should take care of. While assembling the pc or adding or removing components, the wires could prove to be a great deal of stress if they are not managed properly. Make sure that the case has a proper cable management system.
