- Secure PSU: Secure the PSU to the case using screws from the rear.
2.4 Storage Drive Installation (HDD/SSD)
The case supports 1 x HDD and 2 x SSDs.
- Locate Drive Bays: Identify the designated mounting points for 3.5" HDDs and 2.5" SSDs.
- Install Drives: Secure your HDD(s) and SSD(s) using the provided screws or tool-less mechanisms, if available.
2.5 Graphics Card and Expansion Cards
- Remove Slot Covers: Remove the necessary expansion slot covers from the rear of the case.
- Insert Card: Carefully insert your graphics card or other expansion cards into the appropriate PCIe slots on your motherboard.
- Secure Card: Secure the card with screws.
2.6 Cable Management
Utilize the 20mm cable management space behind the motherboard tray to route and tie down cables. This improves airflow and aesthetics.
