Removing the side panel reveals actually how much padding is in this case. The side panel itself is completely covered, minus the line where it would rub against the separator of the hard drive area from the motherboard area.
The nine hard drives and power supply are separated on the bottom of the case while the motherboard and 5.25″ drive bays are found on the upper portion of the case. Five hard drive slots line up closest to the front of the case and then two rows of two bays are found equally spaced apart moving towards the back of the device, giving enough room for the power supply and cabling. More sound dampening foam is found behind these bays, which all point outwards for quick and easy access.
Two smaller cages can actually be removed for even more room for the power supply. Four screws hold the cage to the separator.
The seven 5.25″ drive bays are all pretty open and each have a pre-installed screwless device attached to it. A nice benefit to this case is that you don’t have to remove any steel plates blocking the drive bays, only plastic ones on the bezel. Another layer of foam is also found on the underside of the top of the case.
The motherboard tray is longer than normal trays mainly because it supports Extended ATX (E-ATX) motherboards which are mainly used for servers. It also provides plenty of room for those super long video cards. There are also two holes on the tray which reveal the sound dampeners on the other side panel of the case, but if you really wanted to remove them you’d be able to route some cables behind the tray.
