Operating Instructions
ARGB Lighting Control
The dual ARGB light strips can be controlled to switch between 14 different lighting effects, adjust brightness, color, and sync with your motherboard's RGB software.
Maintenance
Dust Filters
The case features removable dust filters for easy cleaning, helping to maintain optimal airflow and component longevity.Cleaning
To clean the tempered glass panels, use a soft, lint-free cloth and a mild glass cleaner. For other surfaces, a damp cloth is sufficient. Ensure the system is powered off and unplugged before cleaning.
Troubleshooting
Motherboard Fit Issues
If experiencing difficulty fitting your motherboard, particularly with larger models like the MSI MAG B650 Tomahawk WiFi, ensure all standoffs are correctly aligned and consider the adjustable motherboard height options to create more clearance.
GPU Clearance
For very large graphics cards, ensure adequate space, especially if using side-mounted radiators or fans. The adjustable anti-sag bracket can help position the GPU optimally.
Tight Screws
Some screws, particularly those for the backplate, may be very tight. Use an appropriately sized Phillips head screwdriver and apply firm, steady pressure to avoid stripping the screw heads.
