- Install Graphics Card (GPU): Insert your graphics card into the appropriate PCIe slot on your motherboard. The case supports GPUs up to 400mm in length. Ensure it is securely seated and fastened with the retention clip or screw. The case also supports vertical GPU mounting (requires an optional riser cable, not included).
- Install Storage Drives: The case supports 3 x SSDs and 2 x HDDs. Locate the drive bays and mount your 2.5-inch SSDs and 3.5-inch HDDs using the provided screws.
- Install Power Supply (PSU): Mount your power supply unit in the bottom-mounted PSU chamber. The case supports PSUs up to 210mm in length. Secure it with screws from the rear of the case.
- Connect Cables: Connect all necessary power cables from the PSU to your motherboard, GPU, and storage drives. Connect the case's front panel connectors (USB 3.0, audio, power, reset, LED) to the corresponding headers on your motherboard. The pre-installed ARGB fans are typically pre-wired to a controller; connect this controller to your PSU and motherboard's ARGB header for synchronization.
