3. Install the Power Supply (PSU):

   Slide your PSU into the dedicated compartment at the bottom rear of the case. Secure it with screws from the rear. Route the necessary cables through the cable management cutouts.
4. Install Storage Drives:

   Install 2.5" SSDs or 3.5" HDDs into the drive cages or mounting points. The adjustable HDD/SSD cage under the PSU shroud can be repositioned for additional radiator or PSU space if needed.

5. Install Graphics Card (GPU) and Expansion Cards:

   Remove the necessary PCIe slot covers. Insert your graphics card and other expansion cards into their respective slots on the motherboard and secure them with screws. The case supports GPUs up to 344mm in length.

7. Connect Cables:

   Connect all necessary power cables from the PSU to the motherboard, GPU, and storage drives. Connect the front panel I/O cables (USB, audio, power/reset buttons, LED indicators) to the motherboard. Connect the pre-installed ARGB fans and any additional fans to the integrated PWM/ARGB hub, then connect the hub to your motherboard's ARGB and PWM headers.
8. Cable Management:

   Utilize the cable routing channels and tie-down points behind the motherboard tray to manage cables neatly. This improves airflow and aesthetics.

9. Reassemble the Case:

   Once all components are installed and cables are managed, reattach the top panel and the tempered glass side panel, securing them with their respective screws.

Operating Instructions

After successful assembly, connect your peripherals (monitor, keyboard, mouse) and power cable to the system. Press the power button on the front panel to start your computer. The pre-installed ARGB fans will illuminate, and their lighting effects can be controlled via your motherboard's ARGB software or the integrated hub's default settings. Fan speeds can be managed through your motherboard's BIOS/UEFI settings or fan control software, leveraging the PWM functionality of the hub.

Maintenance

Regular maintenance helps ensure optimal performance and longevity of your PC case and components.

• Dust Cleaning: Periodically clean the dust filters located on the front panel and under the PSU. These filters are designed to be easily removable for cleaning. Use compressed air or a soft brush to remove accumulated dust from fans and internal components.
• Cable Management Check: Occasionally check cable routing to ensure no cables are obstructing airflow or fan blades.
• Fan Inspection: Inspect fan blades for dust buildup and ensure they are spinning freely without obstruction.
• Exterior Cleaning: Wipe the exterior of the case with a soft, damp cloth. Avoid abrasive cleaners or solvents.
