5. Operating Instructions

Once assembled, connect your monitor, keyboard, mouse, and power cable to the appropriate ports. Press the power button on the front panel to start your system. Refer to your motherboard and operating system manuals for specific boot-up and software configuration instructions.

6. Maintenance

• Cleaning: Regularly clean the exterior of the case with a soft, dry cloth. For mesh panels, use compressed air to remove dust buildup. Ensure the system is powered off and unplugged before cleaning.
• Airflow: Keep the mesh panels clear of obstructions to maintain optimal airflow and cooling performance.
• Component Checks: Periodically check internal components for dust accumulation and ensure all connections are secure.

7. Troubleshooting

• System Not Powering On: Verify all power connections (24-pin ATX, 4/8-pin CPU, front panel power switch) are correctly seated. Ensure the power supply is switched on and connected to a working outlet.
• No Display Output: Check that the monitor is correctly connected to the graphics card or motherboard (if using integrated graphics) and that the monitor is powered on.
• Overheating: Ensure proper cable management to avoid obstructing airflow. Verify that CPU cooler and any case fans are functioning correctly. Clean dust from mesh panels and heatsinks.
• Loose Connections: If experiencing intermittent issues, power off the system and re-seat all internal cables (SATA, power, front panel).
