- Align the motherboard with the standoffs in the case. The case supports ATX, Micro-ATX, and Mini-ITX motherboards.
- Secure the motherboard with the provided screws.
3. Power Supply Unit (PSU) Installation
- Mount your ATX power supply into the PSU shroud area at the bottom rear of the case.
- Secure the PSU with screws from the rear of the case.
4. Storage Drive Installation
- 3.5" HDDs: Install 3.5" hard drives into the dedicated drive cage located under the PSU shroud.
- 2.5" SSDs: Mount 2.5" SSDs to the dedicated brackets behind the motherboard tray or on top of the PSU shroud.
5. Graphics Card (GPU) Installation

7. Cable Management
Utilize the cable routing cutouts and tie-down points behind the motherboard tray to organize cables for improved airflow and aesthetics.

8. Connecting Front I/O
Connect the front panel cables (USB 3.0, USB 2.0, HD Audio, Power Switch, Reset Switch, Power LED, HDD LED) to the corresponding headers on your motherboard. Refer to your motherboard manual for exact pin layouts.
Operating Your PC Case
Once all components are installed and cables are connected, replace the side panels. Power on your system using the power button on the front I/O panel. The mesh design ensures optimal airflow for cooling your components.
Front I/O Ports:
- Power Button: To turn the system on/off.
- Reset Button: To restart the system.
- USB 3.0 Ports: For high-speed data transfer.
- USB 2.0 Port: For standard USB devices.

Maintenance
Regular maintenance helps ensure optimal performance and longevity of your PC components.
- Dust Filters: The case features removable dust filters on the front, top, and bottom (PSU intake). Regularly remove and clean these filters with compressed air or water (ensure they are completely dry before reinstallation).
- Interior Cleaning: Periodically use compressed air to clear dust from internal components and fans. Ensure the system is powered off and unplugged before cleaning.
- Exterior Cleaning: Wipe the exterior surfaces with a soft, damp cloth. Avoid harsh chemicals that may damage the finish.
Troubleshooting
If you encounter issues, consider the following common troubleshooting steps:
- No Power: Ensure the PSU is switched on, all power cables (24-pin, 8-pin CPU, GPU PCIe) are securely connected, and the front panel power switch cable is correctly attached to the motherboard.
- Fans Not Spinning: Check fan connections to the motherboard or fan controller. Ensure sufficient power is supplied.
- Front I/O Not Working: Verify that all front panel cables (USB, Audio) are correctly connected to the motherboard headers.
- Overheating: Ensure proper fan configuration (intake/exhaust), clean dust filters, and check CPU cooler/GPU heatsink mounting.

- Dust Filter Cleaning: Make cleaning dust filters a routine task (e.g., once a month) to maintain good airflow and prevent dust buildup inside your PC.
- Component Compatibility: Always double-check the dimensions of your CPU cooler, GPU, and PSU against the case's maximum clearance specifications before purchasing.
