4. Setup and Installation
4.1. Unpacking and Preparation
- Carefully remove the PC case from its packaging.
- Inspect the case for any signs of damage during transit.
- Remove all tempered glass panels and the top mesh filter by unscrewing the thumb screws or releasing the latches. Set them aside on a soft, flat surface to prevent scratches.
- Familiarize yourself with the internal layout and included accessories (screws, cable ties, etc.).
4.2. Component Installation
Follow these general steps for installing your PC components. Refer to your individual component manuals for specific instructions.
- Motherboard: Install the necessary standoffs for your motherboard form factor (ATX, Micro ATX). Carefully place the motherboard into the case and secure it with screws.
- Power Supply Unit (PSU): Mount the PSU in the designated bottom compartment. Secure it with screws from the rear of the case.
- Storage Drives: Install 2.5" SSDs and 3.5" HDDs into their respective drive bays or mounting points.
- Graphics Card (GPU) and Expansion Cards: Remove the necessary PCIe slot covers. Insert your graphics card and other expansion cards into the motherboard's PCIe slots and secure them.
- Fans and Radiators: Install additional cooling fans or liquid cooling radiators as desired. The case supports up to a 360mm radiator. Ensure proper airflow direction (intake/exhaust).
- CPU Cooler: Install your CPU cooler according to its manufacturer's instructions. Ensure it fits within the case's maximum CPU cooler height (170mm).
4.3. Cable Management
Utilize the cable routing cutouts and tie-down points behind the motherboard tray to organize cables. This improves airflow and aesthetics. Connect all necessary power and data cables to your components and the front I/O panel.

5. Operation
5.1. Powering On
Once all components are securely installed and cables are connected, replace the tempered glass panels and top mesh filter. Connect your monitor, keyboard, mouse, and power cable. Press the power button on the top I/O panel to start your system.
5.2. Airflow Optimization
The darkFlash DS900 is designed for high airflow. Ensure that fans are configured to create an optimal balance of intake and exhaust. Typically, front and bottom fans are set to intake, while rear and top fans are set to exhaust, creating positive pressure to reduce dust ingress.
6. Maintenance
6.1. Cleaning Dust Filters
Regularly clean the magnetic dust filters located on the top and other panel filters. These can be easily removed, cleaned with water and mild soap, dried thoroughly, and reinstalled. This prevents dust buildup inside the case, which can hinder cooling performance and component longevity.
6.2. General Cleaning
Use a soft, dry cloth to wipe down the exterior of the case, including the tempered glass panels. For stubborn smudges on glass, a glass cleaner can be used sparingly on the cloth, not directly on the glass. Avoid abrasive cleaners or solvents.
7. Troubleshooting
If you encounter issues with your PC build, consider the following common troubleshooting steps:
- No Power: Ensure all power cables (PSU to wall, PSU to motherboard, CPU, GPU) are securely connected. Check the power switch on the PSU.
- Overheating: Verify that all fans are spinning correctly and are oriented for optimal airflow. Ensure CPU cooler and GPU fans are functioning. Check for dust buildup on components and filters.
- Fan Noise: Excessive fan noise can indicate a fan issue or improper mounting. Check if fans are securely mounted and free from obstructions. Consider adjusting fan curves in your motherboard's BIOS/UEFI or software.
- Front I/O Not Working: Double-check that all front panel connectors (USB, audio, power/reset switches, LED indicators) are correctly plugged into the motherboard headers.
- Component Fit Issues: If a component does not fit, refer to the specifications section for maximum clearances (e.g., GPU length, CPU cooler height, radiator size).
For more complex issues, consult the manuals for your individual PC components or seek assistance from a qualified technician.
