Choosing the right ITX case comes down to how much room it leaves for a graphics card, a cooler, and a power supply without crowding airflow. Build goals vary widely in this category, from ultra-portable LAN-party rigs to compact gaming systems built around a full-size GPU.
Component Clearance is the primary category metric here because it reflects how much space a case provides for a graphics card, CPU cooler, and power supply relative to its footprint. A case that scores well on this metric lets builders use stronger hardware without forcing awkward cable routing or thermal compromises.
