- Install the I/O shield that came with your motherboard into the corresponding opening at the rear of the chassis.
- Align your mATX or Mini ITX motherboard with the pre-installed standoffs inside the chassis.
- Secure the motherboard using the appropriate screws. Do not overtighten.
4.3. Power Supply Unit (PSU) Installation
- Position your PSU in the designated bottom compartment of the chassis.
- Ensure the PSU fan is facing downwards (if the chassis has a bottom vent) or upwards, depending on your cooling preference and chassis design.
- Secure the PSU to the chassis using the screws provided with your PSU.
4.4. Storage Drive Installation
The chassis typically includes bays for 2.5-inch SSDs and 3.5-inch HDDs. Refer to your chassis's internal layout for specific mounting points.
- Locate the drive bays or mounting brackets.
- Install your SSDs or HDDs into the appropriate bays/brackets and secure them with screws.
4.5. Graphics Card (VGA) and Expansion Card Installation
- Remove the necessary expansion slot covers from the rear of the chassis.
- Insert your graphics card or other expansion cards into the corresponding PCIe slots on your motherboard.
- Secure the cards with screws to the chassis.
4.6. Connecting Front Panel Cables
Connect the front panel cables (USB, audio, power switch, reset switch, LED indicators) from the chassis to the corresponding headers on your motherboard. Refer to your motherboard manual for exact header locations.
4.7. Cable Management
Utilize the cable routing cutouts and tie-down points behind the motherboard tray to organize and secure cables. This improves airflow and aesthetics.
4.8. Reattaching Panels
Once all components are installed and cables are managed, carefully reattach the side panels and secure them with the thumbscrews.
5. Operating Instructions
5.1. Powering On/Off
- Ensure all external peripherals (monitor, keyboard, mouse) are connected.
- Connect the power cable to the PSU and a wall outlet.
- Press the power button on the front panel of the chassis to turn on your computer.
- To turn off, use the operating system's shutdown function or press and hold the power button for several seconds.
5.2. LED Fan Control
The chassis features an RGB LED Control switch on the front panel. Press this button to cycle through various lighting modes and colors for the pre-installed LED fans.
6. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your chassis and its components.
6.1. Cleaning Dust Filters
- Periodically remove the top magnetic dust filter and the bottom detachable dust filter.
- Clean the filters using compressed air, a soft brush, or by rinsing with water (ensure they are completely dry before reinstallation).
- Reattach the dust filters.
6.2. General Cleaning
- Use a soft, dry cloth to wipe down the exterior surfaces of the chassis, including the tempered glass panels.
- For stubborn smudges on glass, a mild glass cleaner applied to a cloth (not directly to the glass) can be used.
- Avoid using abrasive cleaners or solvents, as these can damage the finish.
7. Troubleshooting
This section addresses common issues you might encounter.
7.1. No Power
- Ensure the power cable is securely connected to both the PSU and the wall outlet.
- Check that the power switch on the PSU itself is in the 'ON' position.
