Inside the Fractal Design R4 Black Pearl
When you remove both side panels you will find that the inside of both have the sound proofing installed from edge to edge inside of the frame of the chassis. On this, the left side panel, there is the ModuVent panel that is at least twice as thick as the deadening material applied to the panel.
Our first look inside the Define R4 is reminiscent of other Fractal Design cases with the white trim in the hard drive bays, expansion slots and the blades of the fans. The wiring is secured by passing in and out of the grommets, while the hardware box takes a ride in the third hard drive slot from the bottom.
At the top of the chassis, near the front, the pair of 5.25" drive bays reside that use thumbscrews for drive or device mounting. The front I/O wiring has plenty of room to easily pass over the top of both bays.
Here is where things get interesting. There are eight 3.5" bays that will allow for both 3.5" hard drives and 2.5" drives as well. The cage is split into two components that allow them to be reconfigured.
One way is to simply remove the pair of thumbscrews holding the top five drives in place, slide out the cage and rotate it ninety degrees if you wish, then at this point you would replace the thumbscrews.
Or if you want, since the top five bays are already lose, take that section out. Then remove the four screws under the case and a pain behind the front bezel, the bottom three drives pull out as well. Water cooling anyone? Also notice the clip style fan mounting for the front of this chassis. You could essentially clip a dual 140mm radiator in here with the fans attached.
