A PC case is intended to house all the components, channel proper airflow, and showcase all the flashy computer parts. Anyone putting together a list of PC components must check out the Corsair 5000X RGB QL Edition, which has dropped to $130 ahead of Black Friday. This is the beefed-up version of the Corsair 4000X, yet smaller than the full-tower Corsair 7000X. Corsair cases are built to last, as they don't cheap out while constructing them, meaning they can charge a premium for their products. For $130, this might be my new favorite PC case for this manufacturer.
