A new generation of style!
The Define R3 case is reaching new heights in combining stylish, contemporary design with maximum functionality and noise absorbing features. The minimalistic, yet stunning front panel design, fitted with noise absorbing material on the inside, creates an aura of exclusivity.
The patent pending feature ModuVent™, in which you can choose whether to have side and top panels open or not, makes the case appealing for users seeking optimal silence, as well as the performance hungry ones.
The sleek black interior is matched with pre-fitted, dense, noise absorbing material on the side panels, efficiently absorbing noise and vibrations. You can fit an astonishing total of eight(!) hard drives into this case, using the user friendly HDD-trays. All painted in a nice white color and using black silicone mounts. The PSU mounts in the bottom of the case, with a convenient pull-out filter beneath it.
Are you one of those people who always end up with a case full of tangled cables? No more. The Define R3 offers a convenient and good looking way of hiding them. The motherboard has rubber covered holes in which you can easily route the cables behind the motherboard.
