4. Power Supply Installation
- Mount your power supply unit (PSU) in the dedicated compartment at the bottom rear of the case.
- Ensure the PSU fan faces downwards (if the case has a bottom vent) or upwards, depending on your cooling preference.
- Secure the PSU with screws from the rear of the case. The case supports PSUs up to 200mm in length.
5. Expansion Card (GPU) Installation
- Remove the necessary PCI-E slot covers from the rear of the case.
- Insert your graphics card or other expansion cards into the motherboard's PCI-E slots.
- Secure the cards with screws. The case supports GPUs up to 340mm in length.
6. Cooling System Installation (Fans/Radiators)
- The case comes with one pre-installed 120mm PWM/ARGB fan at the rear.
- Additional fans (120mm or 140mm) can be installed at the front, top, and bottom.
- Liquid cooling radiators up to 360mm can be installed at the front, and up to 240mm at the top.
- Refer to the diagram for supported fan and radiator configurations.

7. Front Panel Connections
- Connect the front panel cables (Power, Reset, USB 3.0, USB Type-C, HD Audio) to the corresponding headers on your motherboard.
- Consult your motherboard manual for the exact pin layout of these headers.

8. ARGB and PWM Connections
- The pre-installed fan and ARGB LED strip require connection to your motherboard.
- Connect the 4-pin PWM connector from the fan to a compatible fan header on your motherboard for speed control.
- Connect the 3-pin ARGB connector from the fan and LED strip to a 5V 3-pin ARGB header on your motherboard for lighting synchronization. Do not connect to a 12V RGB header, as this will damage the LEDs.

9. Cable Management
- Utilize the cable routing cutouts and tie-down points behind the motherboard tray to organize cables.
- The soft silicone grommets help protect cables and provide a clean look.
- Proper cable management improves airflow and aesthetics.
Operation
1. Initial Power-On
- After all components are securely installed and cables connected, close the tempered glass side panel.
- Connect your monitor, keyboard, mouse, and power cable to the PC.
- Flip the power switch on your PSU to the 'ON' position.
- Press the power button on the top I/O panel of the case to start your system.
2. ARGB Lighting Control
- If connected to a compatible motherboard's 5V 3-pin ARGB header, the lighting of the pre-installed fan and LED strip can be controlled via your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync).
- Refer to your motherboard's manual for specific instructions on using its ARGB control software.
3. Airflow Management
- The mesh front panel is designed for optimal air intake.
- Ensure that intake fans (typically front and bottom) and exhaust fans (typically rear and top) are configured to create positive or neutral air pressure for efficient cooling and dust prevention.

Maintenance
1. Dust Filter Cleaning
- The case is equipped with dust filters on the top and bottom panels.
- Regularly check and clean these filters to maintain optimal airflow and prevent dust buildup inside the system.
- Gently remove the magnetic dust filters and clean them with compressed air or by rinsing with water (ensure they are completely dry before re-installation).
2. Tempered Glass Panel Care
- Clean the tempered glass panel with a soft, lint-free cloth and a non-abrasive glass cleaner.
- Avoid harsh chemicals or abrasive materials that could scratch or damage the glass.
Troubleshooting
- System Does Not Power On:
- Ensure the power cable is securely connected to both the PSU and the wall outlet.
- Verify the PSU switch is in the 'ON' position.
- Check that the front panel power button cable is correctly connected to the motherboard header.
- Confirm all power cables (24-pin ATX, CPU, GPU) are properly seated in the motherboard and components.
- Fans Not Spinning / ARGB Not Lighting Up:
- Check that the fan's PWM connector is securely plugged into a motherboard fan header.
- Verify the ARGB 3-pin connector is correctly attached to a 5V 3-pin ARGB header on the motherboard (not 12V RGB).
- Ensure your motherboard's ARGB software is installed and configured correctly.
- USB Ports Not Functioning:
- Confirm the USB 3.0 and USB Type-C front panel cables are correctly connected to their respective motherboard headers.
- Check your motherboard manual for correct header locations.
- For other component-specific issues, refer to the instruction manuals for your motherboard, CPU, GPU, and other installed hardware.
