Flexibility for individual requirements

The decoupled motherboard tray adapts to suit individual requirements, being completely relocatable and usable as a test bench. You can adjust it to three different heights or install it alongside the left panel in an inverted layout with redefined airflow. It is fully compatible with E-ATX and XL-ATX motherboards.


Impeccable cooling and silence

The three preinstalled Silent Wings 3 140mm PWM fans offer virtually inaudible operation. They are equipped with a smooth-running 6-pole motor, durable fluid-dynamic bearing and airflow-optimized fan blade design. The frame has funnel-shaped air inlets that generate high air pressure.


Generous space for your setups

The installation options are flexible thanks to repositionable single HDD slots. Supports up to 5 HDDs, 10 SSDs and 2 optical drives out of the box. The practical slot covers serve to hide any unused HDD slots and keep the inner workings neat and tidy. This enables you to create systems that are just as individual as you are yourself. 


Offering unexpected possibilities

The PSU shroud offers you a variety of solutions – not just for hiding the PSU and to keep the system neat and tidy. The cover plates are separately detachable, making it possible to install a fan or an SSD on the top of the PSU shroud and leave enough space for a radiator in the front.


A silence concept by the silence experts

With its smart silence concept, Dark Base Pro 900 rev. 2 is the perfect case for the extreme requirements of overclocked systems and super silent water-cooled PCs. It can carry up to seven additional fans, up to four radiators and has noise-reducing vents all around the case that provide ultra-effective full circuit airflow.


Creating separate cooling zones

The eight PWM fan connectors are divided over two rails, and each is switchable between Silence and Performance Mode. This makes it possible to create two cooling zones that can be controlled by just the front panel switch. If you want all fans to run at the same speed, you can switch both channels to the same mode.


A perfect view inside your PC

The case is equipped with an elegant, fully windowed side panel that is made of tinted and tempered glass. The eye-catching internal LED illumination comes in six switchable colors. You can locate the LED strips freely inside the PC case.


Fulfilling practically every desire

The front I/O port offers perfect compatibility for your high-end PC. A connector of USB 3.1 Type C Gen. 2 is supported. Integrated wireless charger for Qi enabled devices such as smart phones.

February 2020

Haven't got time to list the flaws... but haven't got anything good to say, big regrets with both product and company.


September 2019

Upsides for me: (a) support for optical drives, (b) lots of elbow room when building. But the freedom comes with limitations. 1. Space for cable management behind the motherboard is very limited. Plan ahead. 2. The PSU shroud is a pig to fit. A large, smelly pig. Clearly, this is an afterthought. 3. The glass tends to fall off when removing the screws, a hinged solution would be better. 4. The sticky pads on the LED strips don't work. At all. 5. The PSU fitment is just plain freaking weird. 6. The flexibility in layout comes at a price. A very, very high price. Be sure you need it. Don't mistake me, it's a major achievement to put this much flexibility into a case. If you need the flexibility, it can't be beat. But most people simply won't need it.
