Darkflash DS900 Black 7 x 120 mm A-RGB, USB-C, ATX Case

Darkflash DS900 Black is a middle tower case focused on airflow and visual effect, thanks to tempered glass and built-in A-RGB lighting. It supports ATX, Micro ATX, and Mini ITX motherboards, so you can comfortably use it for both compact and more serious configurations. The internal space is generous, with room for a graphics card up to 425 mm and a cooler up to 170 mm, which opens options for massive GPUs and serious air coolers. The built-in 7 A-RGB fans give a strong start to any build without having to immediately think about additional fans.

What you get

With Darkflash DS900, you actually get a ready-made airflow setup: 3 x 120 mm A-RGB on the side, 3 x 120 mm A-RGB on the bottom, and 1 x 120 mm A-RGB at the back, providing stable intake and exhaust for a cooler system under load. The large capacity for additional fans – up to 3 x 120 mm or 2 x 140 mm on top, plus more fans on the sides and bottom – allows you to adjust the airflow according to where your configuration heats up. The tempered glass showcases all the hardware and A-RGB lighting, making the build visually complete right out of the box. You have 2 x 3.5" and 2 x 2.5" drive bays, which is more than enough for a combination of SSD for the system and larger HDD for storage. The I/O panel with USB 3.1 Type-C, USB 3.0, USB 2.0, and HD Audio gives you convenient front access to the most commonly used ports.

• Support for motherboards ATX, Micro ATX, and Mini ITX, providing flexibility in platform choice and future upgrades.
• Form factor Middle Tower, balancing enough space for components and reasonable external size.
• A total of 7 x 120 mm A-RGB fans (side 3, bottom 3, rear 1) are included for good airflow right out of the box.
• Additional fan positions: top 3 x 120 mm or 2 x 140 mm, side 3 x 120 mm, bottom 3 x 120 mm, rear 1 x 120 mm, allowing serious cooling for powerful systems.
• Tempered glass panel that showcases A-RGB lighting and internal hardware in a clean and neat way.
• Support for graphics cards up to 425 mm in length and CPU coolers up to 170 mm, so you can easily fit high-end GPUs and taller air coolers.
• Power supply unit up to 170 mm, without built-in PSU, giving you the freedom to choose a power supply according to your needs and budget.
• Storage configuration with 2 x 3.5" and 2 x 2.5" bays – a convenient combination for SSD + HDD setup.
• I/O panel with USB 3.1 Type-C, USB 3.0, USB 2.0, and HD Audio, so you have modern ports at the front without needing to reach for the back panel.

Who it is suitable for

This case is a good choice if you want a mid-range to high-end gaming or enthusiast build with an emphasis on cooling and aesthetics. It is suitable for configurations with long graphics cards and more serious CPU coolers, as well as for those who value A-RGB and tempered glass. If you are looking for a super-compact or completely minimalist case (without glass and lights), the format and style here might be too much for you.

The combination of 7 included A-RGB fans, support for long GPUs up to 425 mm, and the presence of USB-C at the front makes Darkflash DS900 Black a very sensible foundation for a modern and well-cooled build.
