This is misleading. Although the actual CPU & memory modules may take up
less than a cubic foot of space, they also need power supplies and
a cooling system (immersion). The actual system is much larger.
 
Based on the pictures of the prototype Cray-3 that I saw (Supercomputing
88), the dimensions of the Cray-3 appear to be are around 2.5 feet in
diameter (octagonal shape) and 3 feet high (more or less). This is a
lot more than a cubic foot.
