A Micro ATX (mATX) case is built around a 244 x 244 mm motherboard - larger than Mini-ITX but far more compact than a full ATX tower. That middle ground gives you up to four expansion slots, four RAM slots on most boards, and room for a full-size graphics card in a chassis that fits neatly on or under a desk. It suits gaming rigs, home-office PCs and compact workstations.

Choose by clearance and airflow. Check the maximum GPU length (most mATX cases take 300-380 mm cards), the CPU cooler height, and radiator support before you buy. Mesh-front designs move more air for hot current-generation components. Every case here ships from South African stock with local warranty and fast nationwide delivery.
