5.8 Cable Management
Utilize the cable routing cutouts and tie-down points behind the motherboard tray to organize cables. This improves airflow and maintains a clean interior appearance.
5.9 Final Assembly
Once all components are installed and cables are managed, reattach the tempered glass side panel and secure it with the thumb screws.
6. Operating Instructions
After completing the setup, connect your monitor, keyboard, mouse, and power cable to the system. Press the power button on the front panel to turn on your computer. The pre-installed LED fans will illuminate, providing both cooling and visual effects.
Use the RGB LED Control switch on the front panel to cycle through available lighting modes or turn off the fan LEDs, if supported by the fan controller.
7. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your chassis.
- Dust Filters: The chassis includes a top magnetic dust filter and a detachable bottom dust filter. Regularly remove and clean these filters to prevent dust buildup and maintain airflow.
- Interior Cleaning: Periodically open the chassis and use compressed air to remove dust from internal components and fan blades. Ensure the system is powered off and unplugged before cleaning.
- Exterior Cleaning: Wipe the exterior surfaces, including tempered glass panels, with a soft, damp cloth. Avoid abrasive cleaners.

8. Troubleshooting
If you encounter issues, refer to the following common troubleshooting tips:
- System Not Powering On:
- Ensure the power cable is securely connected to both the PSU and the wall outlet.
- Verify that the PSU switch is in the 'ON' position.
- Check all front panel header connections to the motherboard, especially the power switch pins.
- Confirm the motherboard 24-pin and CPU 4/8-pin power connectors are securely seated.
- Fans Not Spinning/LEDs Not Lighting Up:
- Check fan power connections. Ensure they are properly connected to the motherboard fan headers or directly to the PSU.
- Verify the RGB LED Control switch connection to the motherboard (if applicable).
- Some fans may have specific power requirements; ensure adequate power delivery.
- Limited Space for Components:
- The chassis is compact. Ensure your components (e.g., CPU cooler, graphics card) adhere to the maximum supported dimensions (CPU cooler height: 165mm, GPU length: 255mm).
- For larger components, careful planning and component selection are necessary.
- Poor Airflow/Overheating:
- Ensure all 5 pre-installed fans are operational and correctly oriented for optimal intake and exhaust.
- Clean dust filters regularly.
