So 2GB of memory, 4 cores at ~250Mhz (was the foreground processor the same? Brochure seemed unclear), runs a *nix. About 15 years ahead of a late 90's Pentium I guess, but more ram. Just need the spare 16 square feet of floor space.

It's not that the Cray 2 isn't amazing, it's that modern chip tech puts at least that much power in your pocket, while desktop chips are far faster. Aaaaand - it's all air cooled and apparently effortless, and the CPU does it all with <100W or so, and it's so cheap almost anyone can buy it. Really, that's at least as amazing as the Cray series.
