2. Motherboard Installation
- Install the necessary motherboard standoffs onto the motherboard tray according to your motherboard's form factor (E-ATX, ATX, Micro-ATX).
- Carefully place your motherboard onto the standoffs, aligning the screw holes.
- Secure the motherboard with screws.
- The D5 supports back-connector motherboards, allowing for cleaner cable routing.

3. Power Supply Unit (PSU) Installation
- The D5 features a bottom-mount PSU design with an individual PSU chamber.
- Slide the PSU into its designated compartment from the rear of the chassis.
- Secure the PSU with screws from the rear.
4. Storage Drive Installation
- The chassis supports up to 3 x 3.5" HDDs and 4 x 2.5" SSDs.
- Locate the drive bays and mounting points. Install your storage drives using the provided screws or tool-less mechanisms.

5. Graphics Processing Unit (GPU) Installation
- The D5 features a modular, rotatable PCI-E slot bracket. This allows for both horizontal and vertical GPU mounting without additional brackets.
- For horizontal mounting, remove the necessary PCI-E slot covers and insert your GPU directly into the motherboard's PCI-E slot.
- For vertical mounting, rotate the PCI-E bracket and use a compatible PCI-E riser cable (not included) to connect your GPU to the motherboard.
- A complementary magnetic GPU holder is included to provide additional support for heavier graphics cards.

6. Cooling System Installation (Fans & Radiators)
- The D5 comes with one pre-installed Neptune AN120 ARGB fan.
- The chassis supports extensive cooling configurations:
- Front: 3 x 120mm or 3 x 140mm fans / 280mm or 360mm radiator
- Top: 3 x 120mm or 3 x 140mm fans / 280mm or 360mm radiator
- Rear: 1 x 120mm fan
- Install additional fans or radiators as desired, ensuring proper airflow direction.

Operating Instructions
Once all components are installed and secured, and all cables are connected:
- Ensure all external peripherals (monitor, keyboard, mouse, etc.) are connected.
- Connect the power cable to your PSU and a wall outlet.
- Press the power button on the chassis to start your system.
- The pre-installed Neptune AN120 ARGB fan will illuminate upon power-on. Its ARGB lighting can typically be controlled via your motherboard's software or a dedicated controller (if applicable).

Maintenance
Regular maintenance helps ensure optimal performance and longevity of your D5 chassis and its components.
- Dust Cleaning: Periodically clean dust from the perforated front and top panels, as well as any dust filters, using compressed air or a soft brush. This maintains optimal airflow.
- Exterior Cleaning: Wipe the exterior surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Cable Management Check: Occasionally inspect internal cables to ensure they remain neatly routed and do not obstruct airflow.
Troubleshooting
This section addresses common issues you might encounter with your chassis.
- System Not Powering On:
- Check all power connections, including the PSU to the wall, PSU to motherboard, and front panel power switch cables to the motherboard.
- Ensure the PSU switch is in the "ON" position.
- Poor Airflow/Overheating:
- Verify that all installed fans are spinning correctly and are oriented for proper intake/exhaust.
- Clean any dust buildup on fan blades and filters.
- Ensure no cables are obstructing airflow paths.
- ARGB Fan Not Lighting Up:
- Check the ARGB cable connection from the fan to the motherboard's ARGB header or a dedicated ARGB controller.
- Ensure ARGB software or controller settings are configured correctly.
