Abstract: One embodiment is a computer chassis for housing modules of a computer system. According to this embodiment, the chassis features a chassis base, first and second bays for first and second motherboards, a fan assembly for mounting fans, a backplane for I/O connections mounted to the chassis base, and at least two compartments for electronic components. The first bay and the second bay are laterally adjacent so that, when in use, the first and second motherboards are in substantially the same plane. The fan assembly is mounted to the chassis base so that, when in use, fans in the fan assembly cause airflow in a substantially lateral direction over the first and second bays. The two compartments for electronic modules are laterally to the side of and in substantially the same plane as the first and second bays.

Abstract: One embodiment of the invention is a computer chassis for housing modules of a computer system. According to this embodiment, the chassis features a chassis base, a first tray for a motherboard removably engaged with the chassis base, and a second tray for a motherboard removably engaged with the chassis base. The second tray is oriented above the first tray when engaged in the chassis base. This embodiment also features a plurality of drawers for storage equipment, such as hard drives, where each drawer is removably engaged with the chassis base. The drawers are oriented laterally to the first and second trays in the chassis base.
