PC case ASUS PRIME AP303 Mesh Midi Tower White — ATX/Micro ATX/Mini-ITX, GPU up to 36 cm, PSU up to 18 cm, CPU cooler height 16.5 cm

The ASUS Prime AP303 Mesh is a compact 44‑liter white Midi Tower PC case designed for efficient airflow and flexible component compatibility. It supports ATX, Micro‑ATX and Mini‑ITX motherboards, accommodates graphics cards up to 360 mm long, 360 mm liquid‑cooling radiators up to 60 mm thick, and ATX power supplies up to 180 mm long. The case includes a graphics card bracket and holder, an internal UL‑certified power cable rated for 15 A, and a front USB Type‑C port for high‑speed data transfer.

Advantages

The mesh front panel and support for up to seven fans or a 360 mm radiator provide strong airflow and cooling potential while the compact 44‑liter footprint keeps the build space‑efficient. A reinforced graphics card bracket reduces sag for long high‑end GPUs, and the 15 A internal power cable improves stable power delivery for demanding components. Tool‑friendly drive bays and anti‑dust filters simplify maintenance.

How to use

Install the chosen motherboard and route power and data cables through the provided cutouts to maintain tidy airflow. Mount the power supply (up to 180 mm) in the PSU chamber and secure drives in the 2.5" and 3.5" bays. Fit the graphics card and use the included bracket and holder to minimize sag. If using liquid cooling, ensure radiator thickness does not exceed 60 mm and confirm clearance for fans. Connect front I/O, including the USB Type‑C cable, to the motherboard header before closing the case.

Recommendations

For best thermal performance keep dust filters clean, use at least one intake and one exhaust fan, and verify GPU and radiator clearances before purchase to ensure component compatibility.
