TAIPEI, Taiwan, July 31, 2026 — ASUS today announced the ASUS 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 to provide optimal cooling for the graphics card, reinforced clamp and bracket, and an integrated ARGB light band that works seamlessly with ASUS Aura Sync. To give users additional cooling options, the ASUS Prime AP304 ARGB variant comes with four pre-installed ARGB fans.
A curved-glass panel wraps around the front to the side of Prime AP304, providing a panoramic view of the inside of the case. This glass panel undergoes a five-stage manufacturing process that approaches aerospace standards, including a tempering process that gives it superior strength and durability. This technique helps ensure reliable protection while elevating the DIY experience, offering users an immersive and refined foundation for their build. In addition, the curved glass panel features an easy-detach rail, making removal and reattachment safe and simple.
The Prime AP304 offers broad compatibility, with support for graphics cards up to 420mm long and radiators up to 360mm long. A patented graphics card slot clamp and a reinforced graphics card bracket provide easy and secure installation across a variety of builds. The reinforced graphics card bracket supports cards 300mm to 360mm long and is mounted with screws to help ensure stability, and the clamp enables tool-less installation to make PC building faster than ever.
The I/O panel on the top of the AP304 is designed for both convenience and clean aesthetics, featuring a USB Type-C® port with transfer speeds of up to 20Gbps, while a 33mm cable management compartment behind the motherboard helps keep cables neatly organized. The AP304 Series is also available in black or white, with matching internal I/O cable colors to create a clean, cohesive build.
