Key features
The Prime AP303 accommodates up to a 360 mm radiator with a maximum thickness of 60 mm, giving you the flexibility to install robust AIO cooling solutions or multi-fan radiators. Combined with mesh-front airflow design, the case helps keep thermals under control whether you’re overclocking or pushing workloads.
Engineered to fit GPUs up to 360 mm in length, the case includes a graphics card bracket and holder that prevents sag and maintains PCIe alignment. This reinforcement is ideal for flagship GPUs and multi‑slot coolers, protecting your investment and preserving optimal airflow paths.
Despite its compact 44‑liter footprint, the Prime AP303 supports ATX, Micro ATX and Mini‑ITX motherboards, enabling a broad range of build configurations—from minimalist gaming systems to fully featured ATX rigs—while maximizing usable internal space.
Front-panel connectors feature 1 x headset jack, 2 x USB 3.2 Gen1 ports and 1 x USB 3.2 Gen 2x2 Type-C port, so you can quickly plug in high-speed storage, peripherals or charge devices. The placement keeps frequently used ports within easy reach for everyday convenience.
Built from durable steel with a clean black finish, the Prime AP303 delivers a premium look and feel that complements any setup. The mesh-front design delivers high airflow without compromising on style, while internal layout and cable routing options make tidying and assembling quick and efficient.
