3. Setup and Installation

Follow these steps to install your PC components into the DS900 case.

3.1 Preparing the Case

1. Unpack the Case: Carefully remove the DS900 from its packaging.
2. Remove Side Panels: The tempered glass side panel is typically secured with thumbscrews or a latch mechanism. Remove it to access the interior. The steel side panel on the opposite side should also be removed for cable management.

3.2 Component Installation

1. Motherboard Installation:
   • Install the I/O shield into the rear opening of the case.
   • Align your ATX, Micro-ATX, or Mini-ITX motherboard with the pre-installed standoffs. Ensure all screw holes align.
   • Secure the motherboard with the provided screws.
2. Power Supply Unit (PSU) Installation:
   • The DS900 supports ATX PSUs up to 200mm in length.
   • Install the PSU into its dedicated compartment at the bottom rear of the case, typically from the rear.
   • Secure the PSU with screws.
3. Storage Drive Installation:
   • The case supports 2x 3.5" HDDs and 2x 2.5" SSDs.
   • Locate the drive cages/mounts. For 3.5" HDDs, slide them into the drive cage and secure with screws. For 2.5" SSDs, mount them to the designated trays or locations.
4. Graphics Card (GPU) Installation:
   • The DS900 supports GPUs up to 400mm in length.
   • Remove the necessary PCIe slot covers from the rear of the case.
   • Insert your graphics card into the appropriate PCIe slot on the motherboard and secure it with a screw or latch.
5. Cooling System Installation (Fans/Radiators):
   • The case offers extensive cooling support:
     • Front: 3x 120mm/140mm fans or 240/280/360mm radiator
     • Top: 3x 120mm/140mm fans or 240/280/360mm radiator
     • Rear: 1x 120mm fan
     • Bottom: 2x 120mm fans
   • Install your chosen fans or radiators in their respective locations, securing them with screws.
   • Ensure proper airflow direction (intake/exhaust).

3.3 Cable Management and Front I/O Connections

1. 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.
2. Front I/O Connections: Connect the front panel cables (USB 3.0, USB 2.0, HD Audio, Power Switch, Reset Switch, Power LED, HDD LED) to their corresponding headers on your motherboard. Refer to your motherboard manual for exact pin layouts.

3.4 Final Assembly

1. Once all components are installed and cables are managed, reattach the steel side panel and then the tempered glass side panel.
2. Ensure all screws are tightened securely.

4. Operating Instructions

4.1 Powering On

Press the power button located on the front I/O panel to turn on your computer.

4.2 ARGB Lighting Control

The DS900 supports Addressable RGB (ARGB) lighting. If your motherboard has a 5V 3-pin ARGB header, you can connect the case's ARGB cables to it and control the lighting effects via your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync). If your motherboard does not have an ARGB header, an external ARGB controller (not included) may be required for lighting control.

4.3 Front I/O Ports

The front I/O panel provides convenient access to:

• 1x USB 3.0 port
• 2x USB 2.0 ports
• HD Audio (headphone and microphone jacks)
• Power Button
• Reset Button

5. Maintenance

Regular maintenance helps ensure optimal performance and longevity of your PC components.

5.1 Dust Filters

The DS900 is equipped with removable dust filters on the top and bottom. Periodically remove and clean these filters to prevent dust buildup inside the case, which can hinder airflow and component cooling.

• Gently slide out the filters.
• Clean them with a soft brush or rinse with water (ensure they are completely dry before reinstallation).

5.2 Tempered Glass Panels

Clean the tempered glass panels with a microfiber cloth and a non-abrasive glass cleaner. Avoid harsh chemicals that could damage the glass or coatings.

5.3 Interior Cleaning

Occasionally, use compressed air to blow out dust from inside the case, especially around fans, heatsinks, and other components. Ensure the system is powered off and unplugged before cleaning.

6. Troubleshooting

Here are some common issues and potential solutions:

• PC does not power on:
  • Check if the PSU is properly connected to the wall outlet and switched on.
  • Ensure all power cables (24-pin ATX, 8-pin CPU, PCIe power) are securely connected to the motherboard and components.
  • Verify the front panel power switch cable is correctly connected to the motherboard header.
• Fans are not spinning:
  • Check if fan cables are securely connected to the motherboard fan headers or a fan controller.
  • Ensure the PSU is providing power.
• ARGB lighting is not working:
  • Verify the ARGB cable is correctly connected to a 5V 3-pin ARGB header on your motherboard (not a 12V 4-pin RGB header).
  • Ensure your motherboard's RGB software is installed and configured correctly.
  • If using an external controller, check its power and connections.
• USB ports not functioning:
  • Check if the front panel USB 3.0 and USB 2.0 cables are correctly connected to their respective headers on the motherboard.

8. User Tips

• Optimize Airflow: With support for multiple fans, consider a balanced intake and exhaust fan configuration for optimal cooling performance. Typically, front and bottom fans as intake, and top and rear fans as exhaust.
• Cable Management: Take your time with cable management behind the motherboard tray. This not only improves aesthetics but also prevents cables from obstructing airflow.
• ARGB Sync: If your motherboard supports ARGB sync, connect the case's ARGB cables to the motherboard's 5V 3-pin header to synchronize lighting effects across your system.
• Dust Filter Cleaning: Regularly clean the magnetic dust filters to maintain good airflow and keep the interior dust-free.
