Troubleshooting

Difficulty closing side panels

Ensure all cables are routed behind the motherboard tray and not protruding into the fan zones.

Adjust the integrated anti-sag bracket to provide proper support to the GPU's weight.

High internal temperatures

Verify that the two pre-installed fans are oriented for proper intake/exhaust and confirm that the radiator is not blocking airflow.

Setup, Compatibility & Care

To begin your build, ensure your power supply and GPU lengths are compatible with the specific layout you choose. The case features modular panels that should be removed carefully to expose the interior for motherboard installation. When performing maintenance, clean the external wood panel with a soft, dry cloth; do not use harsh chemicals or excessive moisture, as this may damage the wood finish. Periodically check the pre-installed slim fans for dust accumulation to ensure optimal airflow. Always route cables through the designated management points early in the assembly process to avoid contact with high-heat components.
