An apparatus for controlling the operating conditions of individual electic circuit boards and a circuit board cabinet for holding one or more environmentally controlled circuit packs is provided. The enclosure provides both electronic ports and cooling ports. The cooling ports may be used to circulate liquid or gaseous coolant over the surface of the circuit board thereby dissipating built up heat. The electronic ports allow the board to be externally connected to other electronic components. Additionally, the enclosure provides an electrostatic buffer that protects the enclosed circuit board from electrostatic shock during operation or while the board is being externally handled and stored. Finally, the enclosure provides a barrier against foreign particles such as dust and moisture. The cabinet allows a plurality of circuit boards to be mounted in one cabinet and cooled by a single cooling source. It also provides coolant draining capabilities and a coolant distribution system.
