Object is a very large single computer cabinet. The front half of its depth houses 16 rectangular bays with covers that pop off. Each bay can hold four circuit modules and four smaller slide-out modules that may be drive sleds. The four bays on the upper left are empty. The eight bays on the upper and lower right have small embossed labels reading "cpu." The four lower left bays are labelled "switch." The rear half of the whole cabinet is inaccessible; it presumably houses wiring and power supplies.
