ASUS Prime AP303 Tempered Glass Mid-Tower ATX Gaming Case
90DC00V0-B39010
The ASUS Prime AP303 Tempered Glass is designed for builders who want maximum hardware compatibility in a compact and stylish chassis. With a 44-litre footprint, it accommodates full-size ATX motherboards, powerful graphics cards, large power supplies, and high-performance liquid cooling without sacrificing space efficiency.
Supporting graphics cards up to 360mm in length and radiators up to 360mm with up to 60mm total thickness, the AP303 is ready for today’s flagship gaming hardware. ASUS also includes an integrated graphics card support bracket to reduce GPU sag and improve stability, particularly for large modern graphics cards such as NVIDIA GeForce RTX™ 50 Series models.
Cooling performance is a major focus of the AP303. The chassis supports up to seven fan mounting positions, with space for triple 120mm or 140mm fans along the top and a rear 120mm exhaust fan pre-installed. Quasi-filter mesh ventilation panels maximise airflow while helping minimise dust entering the system.
The front I/O panel includes a high-speed USB 3.2 Gen 2×2 Type-C port capable of up to 20Gbps transfer speeds, alongside two USB 3.2 Gen 1 Type-A ports and a combined audio jack for convenient connectivity. Tool-free side panels simplify upgrades and maintenance, while 34mm of cable management space helps create clean, professional-looking builds.
Constructed with a durable steel frame and a tempered glass side panel, the Prime AP303 showcases your components while maintaining a clean, understated design that fits equally well in gaming setups and professional workstations.
