Patent ID: 8451600

Claim:
A computer system, comprising: a circuit board assembly comprising: a horizontally oriented circuit board; and one or more heat producing components coupled to the horizontally oriented circuit board, at least one of the one or more heat producing components comprising one or more exposed horizontal surfaces; and a chassis comprising: a pair of opposed left and right rails configured to mount on a corresponding pair of opposed left and right rails in a rack; one or more mounting portions coupled to the horizontally oriented circuit board and configured to support the horizontally oriented circuit board in a horizontal orientation during operation of the horizontally oriented circuit board; and one or more heat spreading portions above the horizontally oriented circuit board, wherein at least one of the one or more heat spreading portions is coupled to at least one of the one or more exposed horizontal surfaces of at least one of the one or more heat producing components and configured to transfer heat away from the at least one of the one or more heat producing components, wherein the horizontally oriented circuit board is suspended from the one or more mounting portions such that the horizontally oriented circuit board is below a first heat spreading portion of the one or more heat spreading portions when the pair of opposing left and right rails of the chassis are installed on the corresponding left and right rails of the rack.
