Abstract: A computer system includes a chassis which is generally U-shaped in lateral cross-section and a cover which together define an internal cavity. A fan pack for cooling the computer system is removably disposed within the internal cavity. The fan pack includes three stacked pairs of individual fan units which are disposed in a row within a rectangular housing. The computer system also includes three power supplies for providing power for the computer system, each power supply being slidably disposed within associated power supply receiving channel formed in the chassis. Each power supply includes a housing, power supply electronics disposed within the housing, and a male electrical connector having both alternating and direct current connection capabilities.
