A gaming case must fit the motherboard, graphics card, power supply, cooler, radiators, drives and cables while providing a clear intake and exhaust path.
Use dimensional limits and the planned component layout before comparing glass, lighting, included fans or visual style.

Nominal ATX support does not answer graphics-card thickness, radiator conflicts or connector clearance.
Check length, height and slot thickness with front fans or radiators installed. Side power connectors need extra room for a safe cable bend.
Tower height must sit below the side-panel limit, while a top radiator can overlap memory or motherboard heatsinks. Component drawings reveal conflicts before assembly.
Mesh area, obstruction and fan placement matter more than the number of vents. Fine filters reduce dust while adding resistance and cleaning work.
Match PSU length with drive cages and cable exits in their installed positions. Stiff modular cables can require more rear-panel depth.
A case USB-C port needs a compatible motherboard header to function at its rated mode. Audio, USB-A and button wiring should also match the board.
A good chassis makes filters, panels, drives and cable routes accessible for maintenance.
