The case is compatible with common ATX, Micro ATX and Mini-ITX motherboards and allows flexible fan configurations for targeted cooling.

How to use

Install a compatible motherboard (ATX, Micro ATX or Mini-ITX) onto the standoffs, fit the power supply of PS II type into the designated compartment, and mount drives into the 5.25", 3.5" or 2.5" bays as required. Connect front-panel USB ports to the motherboard header and position optional 60 mm or 120 mm fans in available mounting locations to improve airflow. Route cables neatly to maintain unobstructed air paths and ensure front-to-rear ventilation.

Recommendations

For optimal cooling in this slim tower, use a balanced combination of intake and exhaust fans (for example, one 120 mm intake and one 60 mm exhaust) and prefer 2.5" SSDs when space or vibration is a concern. Verify PSU depth and cable routing before final assembly to ensure compatibility with installed drives and fans.
