Patent ID: 8755192

Claim:
A system, comprising: a rack; one or more computer systems mounted in the rack, wherein at least one of the computer systems comprises: a circuit board assembly; a power supply unit; one or more hard disk drives; and a chassis coupled to the circuit board assembly, the power supply unit, and the one or more hard disk drives, wherein at least a portion of the chassis is made of a shock-absorbing polymeric material configured to protect the circuit board assembly, the power supply unit, and the one or more hard disk drives from damage from shock or vibration, wherein the chassis comprises a top shock-absorbing polymeric portion and a bottom shock-absorbing polymeric portion, wherein the at least one computer system comprises: a first air passage between the top shock-absorbing polymeric portion and the bottom shock-absorbing polymeric portion, wherein the first air passage comprises an air inlet in the chassis at the front side of the rack and an air exit in the chassis at the back side on the rack, wherein the first air passage between the top shock-absorbing polymeric portion and the bottom shock-absorbing polymeric portion is configured to allow air to move through the chassis from front to back, wherein the air moves across the circuit board assembly such that the air removes heat from heat producing components on the circuit board assembly, a second air passage comprises an air inlet in the chassis at the front side of the rack, wherein the second air passage configured to allow air to move through the chassis from front to back, wherein air in the second passage moves across the heat producing components in the power supply unit such that the air removes heat from the power supply unit, and a third air passage downstream from the first air passage and the second air passage, wherein the third air passage is configured to allow air downstream from the circuit board assembly and the power supply unit to move across heat producing components of at least one of the one or more hard disk drives such that the air removes heat from the at least one hard disk drive.
