Overview

A compact mini tower supporting Micro-ATX and Mini-ITX builds with strong airflow and a carry handle. Fits long graphics cards and tall CPU coolers for high-performance small-form-factor systems.

Compact Design With Airflow Focus

The steel and tempered glass chassis measures 386.1 mm deep, 230 mm wide, and 429.4 mm high. A mesh front panel draws cool air directly over components while the glass side window displays the build.

High-End Hardware Compatibility

Accepts Micro-ATX and Mini-ITX motherboards with room for 366 mm graphics cards and 178 mm CPU coolers. The ATX power supply mounts at the rear bottom with a 200 mm length limit.

Flexible Cooling Options

Mount up to six 120 mm or 140 mm fans across front, top, rear, and bottom locations. Front and top panels each support 240 mm radiators for liquid cooling, while the rear fits a 120 mm unit.

Versatile Placement And Connectivity

The case operates horizontally or vertically; the I/O panel relocates to keep the 20 Gbps USB-C, two USB-A ports, and combo audio jack accessible. Thirty millimeters of rear cable space aids routing.
