Ensuring you get the PC case for your gaming setup can be tough, as buyers often have to look through a large number of technical specifications.

These specifications are to ensure that your PC components can fit within this case without limiting the airflow of the case.

These sizes relate to the overall case, with ATX being the largest and Mini-ITX being the smallest. What size you pick is up to you, but bigger isn't necessarily better, according to our friends at Stealth Optional.
