ASUS today announced the Prime AP304, a versatile panoramic ATX case designed to showcase system components with style. It features a patented slot vent with a three-sided ventilation structure for optimal GPU cooling, reinforced clamp and bracket, and an integrated ARGB light band that works seamlessly with ASUS Aura Sync. The ARGB variant includes four pre-installed ARGB fans.

A curved-glass panel wraps around the front to the side, providing a panoramic view. This glass undergoes a five-stage manufacturing process approaching aerospace standards, including tempering for superior strength and durability. The panel features an easy-detach rail for safe removal and reattachment.

The Prime AP304 supports graphics cards up to 420 mm long and radiators up to 360 mm. A patented GPU slot clamp and reinforced bracket (300–360 mm) ensure secure installation, with tool-less clamp for faster builds. The top I/O panel includes a USB Type-C port with 20 Gbps transfer speeds, while a 33 mm cable management compartment keeps cables organized. Available in black or white with matching internal cable colors.
