A rack element for mounting electronic equipment thereon, including: a front portion, a rear portion, and a pair of side portions defining an interior of the rack element therebetween. The interior of the rack element is partitioned into a front section and rear section, wherein the front section defines an air duct and the rear section defines a power distribution section. The air duct has an opening at one end thereof for receiving cooling air from an air conditioning system, and the front portion of the rack element includes a plurality of openings therein for enabling the cooling air from the duct to exit therethrough for cooling equipment mounted therein. The power distribution section includes an opening at one end thereof for enabling power cables to enter the power distribution section for powering equipment when mounted on the rack element.
