Computer case Darkflash DS900 AIR ATX black

Darkflash DS900 AIR is a black ATX computer case designed to combine a modern exterior with practical internal layout. The model features tempered glass on the front and left panels, a bottom-mounted ATX power supply position, and support for ATX, M-ATX and ITX motherboards. The chassis offers space for multiple storage drives and configurable cooling options; fans are not included in the kit.

Advantages

The case provides stable placement through trapezoidal feet with shock-absorbing pads that reduce vibration. A spacious, easy-to-maintain interior supports flexible storage configurations (up to 2 SSDs and 2 HDDs) and long graphics cards. A protective steel mesh at the rear improves ventilation, and the front and left tempered glass panels give the build a clean, uniform appearance. The I/O panel includes USB-C, USB 3.0 and USB 2.0 ports plus LED, Power, Reset and HD Audio controls for convenient access.

• Building ATX, M-ATX or ITX desktop systems

How to use

Install a compatible motherboard (ATX, M-ATX or ITX) onto the standoffs, fit the power supply into the bottom compartment and secure it. Install storage devices into the dedicated SSD and HDD mounts, route cables through the available openings for tidy cable management, and mount fans or radiators according to preferred airflow configuration. Place the case on a flat surface using the trapezoidal feet and ensure the shock-absorbing pads contact the surface to minimize vibrations. Note that fans are not included and must be purchased separately.

Recommendations

For optimal airflow, install front/side intake fans and top/rear exhaust fans; regularly clean the steel mesh and dust filters to maintain cooling efficiency. When using large GPUs or tall CPU coolers, verify clearance against the specified maximum VGA length (425 mm) and CPU cooler height (170 mm).
