4. Maintenance

Regular maintenance helps ensure optimal performance and longevity of your PC components.

4.1 Dust Management

• Periodically clean the mesh front and top panels to prevent dust buildup, which can restrict airflow. Use a soft brush or compressed air.
• Open the side panel and use compressed air to remove dust from internal components, especially CPU coolers, GPU fans, and power supply.

4.2 Cleaning the Side Window

Use a soft, lint-free cloth and a mild, non-abrasive cleaner (or just water) to clean the transparent side window. Avoid harsh chemicals that could scratch or damage the acrylic/tempered glass.

5. Troubleshooting

If you encounter issues, review the following common troubleshooting steps.

5.1 No Power

• Ensure the power supply is switched on and properly connected to a power outlet.
• Verify all power cables from the PSU are correctly connected to the motherboard and components.
• Check that the front panel power button cable is correctly connected to the motherboard's power header.

5.2 Fans Not Spinning

• Confirm that fan power cables are securely connected to the motherboard fan headers or directly to the power supply.
• Check BIOS/UEFI settings to ensure fan control is not set to a mode that prevents spinning at low temperatures.

5.3 Front Panel I/O Not Working

• Ensure all front panel cables (USB, HD Audio, Card Reader) are correctly connected to the corresponding headers on your motherboard.
• Refer to your motherboard manual for correct pin assignments for each header.
