Abstract: A globally cooled computer system for providing liquid cooling to a plurality of electrical components. The globally cooled computer system includes an electronics unit having a plurality of electronics components attached to a plurality of cards and a card cage for providing structural support to the cards, a fluid management unit for pressurizing fluid within the electronics unit, a reservoir for collecting fluid from the electronics unit, a tubing system for distributing the fluid between the electronics unit and the fluid management unit, and a pressure equalization system connecting the electronics unit and the reservoir to equalize internal pressures between them.
