Maintenance
- Dust Cleaning: Regularly clean dust from the case's ventilation areas and internal components using compressed air or a soft brush. This helps maintain optimal airflow and cooling performance.
- Panel Care: Wipe the aluminum and tempered glass panels with a soft, damp cloth. Avoid abrasive cleaners that could scratch the surfaces.
- Component Checks: Periodically check that all internal components (fans, cables, etc.) are securely seated and free from obstructions.

Troubleshooting
- System Not Powering On: Double-check all power connections, including the PSU to the wall outlet, the 24-pin ATX connector, and the CPU power connector on the motherboard. Ensure the power button cable is correctly connected to the motherboard's front panel header.
- No Display Output: Verify that the graphics card is properly seated in its PCIe slot and that the display cable is securely connected to both the graphics card and the monitor. If using integrated graphics, ensure the display cable is connected to the motherboard's video output.
- Overheating Issues: Ensure all case fans and CPU cooler fans are spinning correctly. Check for dust buildup that might impede airflow. Verify that thermal paste is properly applied to the CPU.
- Loose Components: If experiencing intermittent issues, power down the system and re-seat all major components (RAM, GPU, storage drives) to ensure they are firmly connected.
