To install the motherboard, first remove both side panels of the case. Ensure the standoffs are correctly positioned for your motherboard size (ATX, Micro-ATX, etc.). Align the motherboard with the I/O shield and standoffs, then secure it using screws provided with the case.
Utilize the ample space behind the motherboard tray for routing cables. Use the integrated Velcro straps and cable tie points to secure cables neatly. This not only improves aesthetics but also optimizes airflow by reducing clutter inside the case.
The Dark Base 900 supports up to 7 additional fans. Use the included fan brackets to mount them at the top, front, or bottom of the case. Make sure to connect them to the fan controller or directly to the motherboard for power and speed regulation.
Begin by determining radiator placement (top, front, or bottom). Remove any necessary drive cages for clearance. Secure the radiator and fans using the appropriate screws. Connect tubing to the CPU block and ensure all connections are tight to prevent leaks.
The case includes removable dust filters at the front and bottom. To access, gently pull out the front panel to remove the front filter. For the bottom filter, slide it out from the case’s underside. Clean using compressed air or a damp cloth.
Remove the side panels and locate the drive cages. Slide out the desired cage, mount the drive using screws or tool-less holders, and reconnect power and data cables. Slide the cage back into place and secure it.
Yes, the case supports vertical GPU mounting. Remove the horizontal PCI slot covers and install the vertical mounting bracket. Attach the GPU to the bracket, ensuring it's secure, and connect necessary power cables.
Check all power connections from the PSU to components. Ensure the PSU switch is on and check the power cable and outlet. If issues persist, test the PSU with a different system or use a PSU tester to ensure proper functionality.
Regularly clean dust filters and internal components using compressed air. Ensure all fans and cooling systems are functioning properly. Check and tighten any loose screws or fittings, and keep cables managed to prevent obstruction of airflow.
Ensure there is a balanced intake and exhaust airflow by positioning fans accordingly. Keep the interior clean and organized to prevent airflow blockages. Consider adding additional fans or upgrading to high-performance models if necessary.
