How to use

Install a compatible Mini-ATX, Micro ATX or ATX motherboard on the provided standoffs, mount the power supply in the front-mounted compartment, and position storage drives in the 3.5" or 2.5" bays. Configure airflow by installing up to three 120 mm fans in the front and rear and select 120/140 mm fans for the top if additional exhaust or intake is required. Route cables through available openings to maintain unobstructed airflow and close the tempered side window for an assembled appearance. Verify clearances for long graphics cards and CPU coolers before final assembly.

Recommendations

For balanced cooling, use front intake fans and a top or rear exhaust configuration; choose quality 120/140 mm fans for quieter operation. Place SSDs in the 2.5" bays for the operating system and frequently accessed applications, and use the 3.5" bays for bulk storage drives. Check motherboard standoff positions and cable routing to ensure secure installation and unobstructed airflow.
