How to use

Install the chosen motherboard (ATX, micro-ATX or mini-ITX) onto the standoffs and secure it with screws. Mount the power supply in the side-mounted ATX position and connect power cables through the dual-chamber routing area to improve cable management. Place storage devices into the combo cage for 3.5" or 2.5" drives and secure them. Install the graphics card (up to 334 mm) and cooling components; if using liquid cooling, mount a radiator up to 240 mm in a supported location, observing the maximum radiator thickness (305×120×52 mm). Reattach tempered glass panels after cable routing and component installation, and connect front I/O to the motherboard headers.

Recommendations

For optimal airflow, use a balanced intake and exhaust fan configuration and keep the magnetic top dust filter clean. When building with mini-ITX motherboards, use the removable adapter piece to increase clearance and improve component fitment.
