Computer case Darkflash DS900 ATX White

The Darkflash DS900 ATX White is a mid-tower computer case designed for builders who need a balance of style, expandability and airflow. The white finish and double tempered glass walls offer wide visibility of internal components while the interior layout supports ATX, Micro-ATX and Mini-ITX motherboards. The case is engineered for effective cooling and flexible system configuration, with support for multiple fan positions and water-cooling radiators. Note: fans are not included in the kit.

Advantages

The DS900 combines a panoramic tempered glass aesthetic with a durable 0.5 mm SPCC steel structure that provides stable support for heavy components. Its layout accommodates long graphics cards and tall CPU coolers, while a bottom-mounted power supply bay and dedicated cable management paths promote tidy builds. The front I/O includes a USB-C port for fast data transfer, and dust filters help keep internal components cleaner for longer service life.

Suitable for

• Gaming PC builds with long graphics cards and high-performance cooling
• Custom workstations requiring multiple storage devices and expansion cards
• Showcase builds where component visibility through tempered glass is desired
• Water-cooling setups and high-airflow configurations

How to use

Install the motherboard according to its form-factor standoffs, route cables through the provided channels and secure the power supply in the bottom bay. Fit drives into the dedicated 3.5" and 2.5" mounts and position the graphics card within the available 425 mm clearance. Plan cooling by installing fans or radiators at the top, side, rear and PSU/HDD locations depending on your airflow or water-cooling configuration. Use the tempered glass panels to access and show components while maintaining secure fastening to prevent vibrations.

Usage recommendations

To achieve optimal cooling and component longevity, combine front/side intake fans with top/rear exhaust fans and keep dust filters clean. Verify CPU cooler height and GPU length against the listed maximums before final assembly, and consider using the USB-C front port for fast external storage or peripherals.
