Claim:
A rack system for housing computers, comprising: a rack assembly configured to support a first plurality of computers in a first stack; and at least one air deflection assembly mounted to the rack assembly for redirecting a substantially horizontal airflow emerging from each of the first plurality of computers, wherein the substantially horizontal airflow is redirected by the at least one air deflection assembly to a substantially vertical output airflow that flows within an exhaust plenum laterally adjacent to the first stack; wherein the exhaust plenum is for receiving the substantially horizontal airflow emerging from each of the first plurality of computers and directing the substantially vertical output airflow out of an exhaust port of the rack system; and wherein the rack assembly is further configured to support a second plurality of computers in a second stack such that the back sides of the computers in the first stack face the back sides of the computers in the second stack and the exhaust plenum is disposed between the back sides of the computers in the first stack and the back sides of the computers in the second stack.
