Route cables behind the motherboard tray and use the available cutouts for power and front-panel connectors. Connect the pre-installed front fans to the motherboard fan headers or a fan controller for synchronized speed control. After installing the graphics card and other expansion cards into the rear slots, replace the tempered glass side panel to complete the build.

Recommendations

For effective cooling, maintain unobstructed front intake airflow and ensure rear exhaust fan operation. Use the available USB 3.2 Gen 1 ports for external SSDs or high-speed peripherals. When selecting storage and expansion components, verify clearance for long graphics cards and CPU coolers within the case dimensions. Regularly clean dust from the front fan intakes and filters to sustain airflow performance.
