A cabinet for a central processing unit, made up of a card cage and refrigeration unit, for mounting and cooling electronic components on a group of vertically-aligned, closely-spaced circuit boards. A source of recirculating, forced, refrigerated air is employed to remove the heat from the highly concentrated electronic components. For ease of maintenance, the refrigeration unit and the power supply unit take the form of independently removable modules, and the removable circuit boards are mounted in a readily accessable card cage which incorporates formed card guides which facilitate card removal and insertion.
