The ASUS Prime AP303 is a compact ATX PC case for builders who want room for powerful components in a 44-litre footprint. Its tempered glass side panel suits a clean showcase build, while support for ATX, Micro-ATX and Mini-ITX motherboards gives you flexibility when choosing a platform.

The case can accommodate graphics cards up to 360 mm long, an ATX power supply up to 180 mm long and a top radiator up to 360 mm. ASUS also includes a graphics card bracket and holder to help keep a supported card firmly mounted. Cooling options include space for up to seven fans, with one 120 mm rear fan pre-installed. The front panel provides a 20 Gbps USB Type-C port alongside two USB 3.2 Gen 1 ports.
