The drives are thereby tools installed in the various slots, which are decoupled completely over silicone anti-vibration bars and therefore prevent transmission of vibrations to the cages. In addition, the slots can be removed individually, thus allowing the option of an increased space for graphics cards or water cooling.

The space also falls for the rest of the hardware particularly lush from, because graphics cards can be installed up to a length of 325 mm. Without HDD slots, this space expands even to a whopping 470 mm. CPU cooler may in DarkBase 900 maximum 185 mm high and power supplies from 150 - be 184 mm long.

At the back, however there is room for a 140mm radiator and the floor could accommodate a 280-Radiator. Several smaller radiators can of course also install it in place of the great.

The integrated PWM Hub and manual fan control can be a maximum of three PWM and three 3-pin fan control. An optimum air flow is ensured, which can be adjusted according to the needs of the user.
