An enclosure comprises first and second sections formed of a transparent material, a plurality of wall sections, a plurality of vent holes, a hinge, a cable access and a lock. The wall sections are joined to the first section to form the enclosure. The vent holes are formed in the wall sections to provide thermal flow through the enclosure. The hinge connects the second section to one of the plurality of wall sections to form a door in the enclosure. The cable access is located to allow authorized power and data connections within the enclosure when the door is in an open position, and sized to prevent unauthorized data connections within the enclosure when the door is in a closed position. The lock secures the enclosure by locking the door in the closed position.
