How to use

Install a compatible ATX or Micro-ATX motherboard on the standoffs, fit an ATX power supply into the designated bay, and mount storage drives into the 3.5" and 5.25" cages. Connect the front-panel USB ports to the motherboard headers and position cooling fans in the available front/side and rear mounts for optimal airflow. Route cables neatly to preserve internal space and ensure unobstructed ventilation.

Recommendations

For effective cooling, install up to three 120 mm fans at the front/side and an 80 mm fan at the rear. Use cable ties or routing channels to keep airflow paths clear, and verify motherboard standoff positions before securing the board. The case is best paired with an ATX power supply of appropriate length for the chosen components.
