Compact ATX build platform

The ASUS AP303 Ice Cube is a white 44.3 litre chassis that accepts ATX, Micro-ATX and Mini-ITX motherboards. Its steel, plastic and tempered-glass construction provides a side-panel window for component visibility. Two 20 Gbps USB 3.2 Gen 2 Type-C ports, two USB 3.0 ports and a 2-in-1 audio jack sit on the front panel.

Cooling and GPU clearance limits

The case supports top radiators up to 360 mm, 280 mm and 240 mm, plus a rear 120 mm radiator. Fan mounts include three 140 mm or three 120 mm positions on top, one 120 mm rear and three 120 mm bottom slots. Graphics cards up to 360 mm long fit, while CPU coolers are limited to 165 mm height and power supplies to 180 mm length.

Straightforward assembly with cable space

A removable bottom dust filter simplifies cleaning during and after the build. Up to 34 mm of cable-management depth behind the motherboard tray eases routing. Builders who need more than one 3.5-inch drive or additional 2.5-inch bays will find the single 3.5/2.5 bay and two dedicated 2.5-inch bays restrictive.

Questions about this item

Which colour option should I pick for the AP303 Ice Cube?

The case comes in black or white; choose white for a bright interior that shows RGB lighting clearly, or black for a stealthier look.

What does the 360 mm GPU limit mean when I install a graphics card?

Any card up to 360 mm long will fit, so most triple-fan models go in without hitting the front panel or drive cage.

How fast are the front USB-C ports in real use?

Each front USB-C port runs at 20 Gbps via USB 3.2 Gen 2, so large file transfers hit the drive’s own speed ceiling, not the port.
