The ASUS Prime AP303 is a masterclass in space efficiency, packing massive potential into a compact 44-liter ATX footprint. Engineered for enthusiasts who demand high-end performance without the bulk, this chassis accommodates graphics cards up to 360mm long and radiators up to 360mm, ensuring your system stays cool under the most demanding workloads.
Stability is at the core of the AP303 design. It features a robust graphics card bracket specifically designed to support the weight of modern GeForce RTX 50 Series cards, effectively eliminating sagging and movement. To ensure consistent power delivery for high-wattage builds, the case includes a UL-certified internal power cable capable of handling 15 amperes.
Beyond performance, the AP303 prioritizes user experience with thoughtful features like a 34mm-wide cable management compartment behind the motherboard tray, keeping your build clean and organized. The tool-free side panels allow for quick, secure access to your components, while the metallic quasi-filter mesh panels provide an optimal balance between airflow and dust protection.
