When evaluating gaming cases, prioritize Motherboard Compatibility (E-ATX, ATX, Micro-ATX, or ITX) to ensure the chassis fits the intended build. Thermal Management is critical; look for cases that support at least 360mm AIO liquid cooling radiators and have high-airflow mesh panels. Additionally, verify the GPU Clearance (length) to accommodate modern high-end graphics cards, which often exceed 330mm, and ensure there is sufficient Cable Management Space (at least 20-25mm behind the motherboard tray) to maintain clean aesthetics and airflow.
