How to use

Install an ATX motherboard and ATX power supply into the chassis using the provided standoffs and mounting points. Mount hard drives in the appropriate 3.5" or 2.5" bays and secure the external 5.25" device if required. Connect front-panel USB 3.0 to the motherboard header for front access. Fit 60–80 mm fans in the supported positions to ensure proper airflow; verify fan orientation to achieve intake and exhaust balance. Slide the chassis into the rack and fasten with rack screws at the designated mounting points.

Recommendations

For reliable operation, use quality ATX power supplies matched to your component load, populate drive bays with vibration-damped mounts where available, and maintain active airflow by installing fans in both intake and exhaust positions. Regularly check dust filters and clean the interior to prevent thermal buildup in compact rack environments.
