Mount 3.5" or 2.5" drives into the corresponding bays using the drive trays or screw mounts provided by the case. Connect drives to the motherboard and the included 350 W power supply using the appropriate SATA or power connectors. Attach the rear 120 mm fan to the motherboard fan header or power connector as appropriate. Use the front USB 3.2 Gen 1 Type-A ports for connecting external storage, flash drives, or local management devices.

Recommendations

For reliable operation, ensure adequate ventilation around the case and avoid obstructing the rear fan intake. Match component power requirements to the included 350 W power supply capacity; consider a higher-capacity PSU if planning to populate all drive bays and add additional power-hungry components. Use quality SATA cables and secure drive mounting to minimize vibration and improve drive longevity.
