How to use

Install the motherboard on the provided standoffs and secure it with the appropriate screws. Mount the power supply in its designated compartment and connect power cables to the motherboard and peripherals. Fit storage drives into the drive bays and secure expansion cards into the PCIe slots. Route cables through the case routing channels to keep airflow clear, then install case fans or cooling solutions according to the available mounting points. After all components are secured and cables connected, verify front-panel connector placement and perform a first power-on test to ensure the system posts correctly.

Recommendations

For reliable operation, use standard ATX-compatible components and check component clearance for long graphics cards or tall CPU coolers. Maintain dust filters and periodically clean fan intakes to preserve cooling performance. When planning upgrades, confirm the case's internal dimensions and mounting options to ensure compatibility with new components.
