The SilverStone Fortress FT05B is an unusual ATX case, as it has pretty much all the usual parts and features however they are not in the usual locations. Where the FT05B-W departs from the norm is the way the motherboard is rotated 90 degrees so the I/O panel sits at the top of the case. This means that cooling air that usually enters from the front of the case is actually drawn in from the bottom and then blown vertically up the case by the two huge 180mm Air Penetrator fans (that’s £30 right there) that occupy the floor of the case. When you consider that hot air rises this arrangement makes perfect sense, however it also makes the design of the case a little complicated.
