The modules were held together in an aluminum chassis known as a "brick". The bricks were immersed in liquid [[fluorinert]] for cooling, as in the Cray-2. A four-processor system with 64 memory modules dissipated about 88&nbsp;kW of power.{{sfn|Lester|1993}} The entire four-processor system was about {{convert|20|in|mm}} tall and front-to-back, and a little over {{convert|2|feet}} wide.{{sfn|Brochure|1993|p=15}}

For systems with up to four processors, the processor assembly sat under a translucent bronzed acrylic cover at the top of a cabinet {{convert|42|in|m}} wide, {{convert|28|in|m}} deep and {{convert|50|in|m}} high,{{sfn|Brochure|1993|p=15}} with the memory below it, and then the power supplies and cooling systems on the bottom. Eight and 16-processors system would have been housed in a larger octagonal cabinet. All in all, the Cray-3 was considerably smaller than the Cray-2, itself relatively small compared to other supercomputers.{{sfn|Brochure|1993|p=15}}

In addition to the system cabinet, a Cray-3 system also needed one or two (depending on number of processors) ''system control pods'' (or "C-Pods"), {{convert|52.5|in|m}} square and {{convert|55.3|in|m}} high, containing power and cooling control equipment.{{sfn|Brochure|1993|p=15}}
