Every cubic millimeter of space has been optimized, and the kicker is that the entire PC is cooled by one exhaust fan and a blower for the GPU's VRM. The system takes advantage of convection cooling and optimized vents, so that neither the CPU nor the GPU, which are both water cooled, actually have fans directly attached to their radiators. The result is quite impressive, a fully functional gaming PC that is not only small but also stylish.
