5.2 Panel Cleaning
The modular panels, including the tempered glass side panel, can be easily removed for thorough cleaning. Use a soft, lint-free cloth and a mild cleaning solution (e.g., glass cleaner for tempered glass) to wipe down surfaces. Avoid abrasive materials that could scratch the panels.
6. Troubleshooting
This section addresses common issues you might encounter during assembly or use of your QUBE 500 case.
- Cable Management: If you experience difficulties with cable management, especially with larger ATX power supplies or long graphics cards, consider using an SFX power supply for more room. Utilize the dedicated cable management channels behind the motherboard tray.
- Component Fit: Ensure all components adhere to the maximum clearance specifications (CPU cooler: 164mm, GPU: 365mm, PSU: 332mm). Double-check component dimensions before installation.
- Side Panel Security: If a side panel feels insecure or does not click into place firmly, re-examine the mounting points. Ensure all screws (if applicable) are properly tightened and that no cables are obstructing the panel's closure.
- Airflow Concerns: If you notice higher than expected component temperatures, verify that all fans are correctly installed and oriented for optimal airflow. Ensure dust filters are clean and not obstructing air intake.
