A junction-less transistor having an reverse polarity structure includes a substrate, a semiconductor body, a gate and a gate insulation layer. A face member formed primarily of a metallic material forms the face, and a body member is connected to the face member and extends rearward from the face member to form at least a portion of the body. This presents a problem for tooling vendors because most server owners do not want anything other than their applications running within the AppServer virtual machine. The chassis is configured such that a second portion of the gas can flow within the second flow pathway between the intake region and a second end portion of the line card such that the second portion of the gas flows across the second end portion of the line card in a second direction opposite the first direction.
