5.7. Cable Management
Utilize the cable routing cutouts and tie-down points behind the motherboard tray to manage cables. This improves airflow and aesthetics.
- Connect all necessary power cables from the PSU to your components (motherboard, GPU, drives).
- Connect front panel cables (USB, audio, power/reset switches) to the motherboard headers.
- Route cables neatly using cable ties to prevent obstruction of airflow.

8. Maintenance
Regular maintenance helps ensure the longevity and performance of your PC components.
- Dust Cleaning: Periodically clean dust filters and internal components using compressed air. Ensure the system is powered off and unplugged before cleaning.
- Fan Inspection: Check fans for dust buildup and ensure they are spinning freely.
- Cable Management: Re-evaluate cable routing if you notice any airflow issues or component overheating.
9. Troubleshooting

- No Power: Ensure the PSU is switched on, the power cable is securely connected, and all internal power cables (24-pin ATX, 8-pin CPU, GPU power) are properly seated.
- No Display: Verify that the monitor cable is connected to the graphics card (not the motherboard I/O, unless using integrated graphics) and that the graphics card is fully seated in its PCIe slot.
- Fans Not Spinning: Check fan connections to the motherboard or fan controller. Ensure the PSU is providing power.
- System Instability: Double-check all component installations, especially RAM and CPU. Ensure adequate cooling.
