A method and system of cooling a server rack unit is described herein. A server rack for housing certain devices may be configured to receive a first air flow at a server rack front. Each device may form a wall at the back of the device creating a channel between the wall and the server rack back. The camber may collect warm air created by the first air flow as it extends over the at least one server. A first surface of the server may define at least one server rack opening allowing the warm air in the channel to exit the server rack.
