Connect the front panel cables to your motherboard:
- УСБ 3.0: Connect the USB 3.0 header cable to your motherboard's USB 3.0 port.
- УСБ типа Ц: Connect the USB Type-C header cable to your motherboard's Type-C port (if available).
- ХД аудио: Connect the HD Audio cable to your motherboard's audio header.
- Power SW, Reset SW, HDD LED: Connect these small pinouts to the corresponding headers on your motherboard.
- АРГБ заглавље: Connect the ARGB cable from the fan hub to your motherboard's 5V ARGB header for software control. If left unplugged, the case's dedicated RGB button will control lighting.

- ARGB осветљење: The ARGB fans can be controlled in two ways:
- Контрола софтвера матичне плоче: Connect the ARGB cable from the fan hub to your motherboard's 5V ARGB header. Use your motherboard's RGB software to customize lighting effects.
- Case Button Control: If the ARGB cable is not connected to the motherboard, use the dedicated RGB button on the top I/O panel to cycle through pre-set lighting modes. Press and hold the RGB button for 3 seconds to switch between software control and case button control (if connected to motherboard).
4. Одржавање
Regular maintenance helps ensure optimal airflow and extends the lifespan of your components.
