Overview

A mid-tower chassis with a mesh front, tempered glass side panel, and four pre-installed 140 mm D-RGB fans. It supports E-ATX boards, 360 mm top radiators, and back-connect motherboard designs.

Airflow and Cooling Capacity

The mesh front panel draws cool air through four pre-installed 140 mm D-RGB fans. The interior supports up to seven fans total, including three 140 mm units at the front, two 140 mm or three 120 mm fans at the top, and one 120 mm or 140 mm fan at the rear. A 360 mm radiator fits in the top position for liquid cooling.

Hardware Compatibility

The case accepts ATX, E-ATX, Micro-ATX, and Mini-ITX motherboards. Graphics cards up to 415 mm long and CPU coolers up to 184 mm tall are supported. ATX power supplies up to 270 mm deep install behind a PSU shroud. Drive capacity includes two 3.5-inch and two 2.5-inch bays.

Back-Connect Motherboard Support

The chassis is designed for motherboards with rear-mounted connectors, including ASUS BTF, MSI Project Zero, and Gigabyte Project Stealth. This layout routes cables behind the board for a cleaner internal appearance and improved airflow paths.

Build Features and Connectivity

A full-length tempered glass side panel showcases the build, illuminated by a D-RGB strip along the edge. The top-mounted I/O panel provides a power button, HD audio combo jack, two USB 3.0 Type-A ports, and one USB 3.1 Type-C port. Dust filters and cable management tie-downs are included.
