Abstract

A computer mother board is housed in a chassis that has a number of expansion board guides along a back panel of the chassis and a power supply with a cooling fan. The mother board is rectangular with its short dimension being 8 inches and its long dimension being as 13 inches so that it fits into the chassis of existing computers. The motherboard is positioned in the chassis such that the long dimension is along the back panel of the chassis, which means that the motherboard is rotated 90 degrees from the orientation of conventional motherboards. The short dimension accommodates a number of expansion card connector sockets perpendicular to the long dimension such that the connector sockets are in alignment with the expansion board guides along the back panel of the chassis. A central processing unit socket is located near the power supply fan for more efficient cooling. Input/output connectors sockets are located along the long dimension such that the input/output connector sockets are in alignment with openings in the back panel.
