• Discharge static electricity by touching a grounded metal object before handling components.

4.2. Opening the Case

1. Place the case on a flat, stable surface.
2. Carefully remove the four thumb screws securing the tempered glass side panel.
3. Gently lift and remove the tempered glass panel, setting it aside on a soft, non-abrasive surface to prevent scratches.
4. Remove the solid metal side panel by unscrewing its two thumb screws and sliding it backward.

4.3. Motherboard Installation

• Install the I/O shield into the rear opening of the case.
• Align your motherboard with the pre-installed standoffs. Ensure the motherboard type (Mini ATX, ATX) is compatible.
• Secure the motherboard with the appropriate screws from the accessory box.

4.4. Power Supply Unit (PSU) Installation

• Position the PSU in the dedicated compartment at the bottom rear of the case.
• Ensure the PSU fan faces downwards (if there's a filtered vent) or upwards, depending on your cooling preference.
• Secure the PSU with screws from the accessory box.

4.5. Storage Drive Installation

The case supports both 3.5-inch HDDs and 2.5-inch SSDs.

3. Reattach the filters to their respective positions.

6.2. General Cleaning

• Use a soft, damp cloth to wipe down the exterior surfaces of the case. Avoid harsh chemicals.
• For the tempered glass panel, use a glass cleaner and a microfiber cloth to avoid streaks.
• Periodically use compressed air to clear dust from internal components and fan blades.

7. Troubleshooting

7.1. No Power After Assembly

• Check all power connections: PSU to wall outlet, PSU to motherboard (24-pin and CPU 8-pin), and GPU power cables.
• Ensure the front panel power switch cable is correctly connected to the motherboard's front panel header.
• Verify the PSU switch is in the 'ON' position.

7.2. Excessive Noise

• Identify the source of the noise (fans, HDD, etc.).
• Ensure all fans are securely mounted and free from cable obstructions.
• Check if fan speeds are set appropriately in your motherboard's BIOS/UEFI or operating system software.

7.3. Overheating Components

• Verify that all case fans are spinning and oriented correctly for optimal airflow (intake at front, exhaust at rear/top).
• Clean any clogged dust filters.
• Ensure CPU cooler and GPU fans are functioning correctly.
