Abstract
A computer system including a chassis of substantially rectangular cross section suitable for receiving a circuit board. A rear face of the chassis includes upper and lower exhaust ports. A CPU board including one or more processors may be housed within the chassis. The expansion board is suitable for receiving a plurality of expansion cards via connectors attached to the board. The expansion board includes at least one void for facilitating air flow and is housed within the chassis wherein a rear side of the board is proximal to the rear face of the chassis between the upper and lower exhaust ports. An air moving device is positioned within the chassis for directing air flow across the expansion board toward the rear face of the chassis and, via the at least one void in the expansion card, through the upper and lower exhaust ports. Preferably, at least one of the voids comprises a notch formed in the perimeter of the expansion board wherein the interior surface of the chassis together with the notched void cooperatively define a passage for facilitating air flow. In the preferred embodiment, the computer system further includes a plurality of expansion cards that are received by t…
