ASUS debuts Prime AP303 compact ATX case
ASUS introduced the Prime AP303, a 44-liter ATX mid-tower chassis designed to fit full-size motherboards and graphics cards extending 360 millimeters while maintaining compact dimensions. The enclosure comes in four configurations, pairing tempered glass or metal mesh side panels with black or white finishes, accommodating power supplies measuring 180 millimeters and radiators reaching 360 millimeters in length across seven fan mounting positions.
The manufacturer integrated a reinforced GPU bracket supporting cards from 310 to 360 millimeters to prevent sagging with high-end models, including the ROG Astral GeForce RTX 5090, while a UL-certified 15-ampere internal cable handles front-mounted ATX power supply connections. Tool-free side panel access and 34 millimeters of cable management space behind the motherboard tray simplify assembly, with a square-pattern metal grille managing airflow and dust filtration across all variants.
Front connectivity includes USB 20 gigabits-per-second Type-C alongside dual Type-A ports and 3.5-millimeter audio jacks for headphones and microphones.
