How to use

Install a compatible ATX, M-ATX or ITX motherboard and route cables using the chassis openings and tie-down points. Mount storage drives in the provided 2x HDD and 2x SSD brackets and install the power supply in the bottom compartment. Populate fan positions or radiators according to cooling requirements — the case accepts multiple 120 mm fan locations and a 360 mm radiator. Use the front I/O USB-C port for high-speed device connections and control ARGB lighting through the motherboard or included fan controller if applicable.

Recommendations

For optimal airflow, configure intake fans at the front and side and exhaust fans at the top and rear. Verify GPU length (max 425 mm) and CPU cooler height (max 170 mm) before assembly. Regularly clean dust filters to maintain cooling performance. If using RGB effects, connect fans to a compatible ARGB header or controller to synchronize lighting.
