That's right, you *did* mention 2 or 4 U servers. Really, for what you want, you can get in a 1U box.
the decision of 1U vs 2U is largely driven by disk and IO card requirements.
a 1U Intel server can take up to 4 3.5" or 8 2.5" hotswap drives, 2 CPU sockets (4 to 24 cores total), 18 or 24 dimms, and has 1-2 PCI-E slots
a 2U can take as many as 12 3.5" or 24 2.5" drives, the same CPU/memory, and typically 4 PCI-E slots, although I've seen more.
3U/4U stuff is generally quad socket and a lot more expensive.
Heh, heh. We have a cluster of 22 servers. One has "only" eight cores. 11 more, I think, have 48 cores, and the latest 10 have 64 cores; I think that's 12 core dies ("chips"). Everything except the first are all 1U.
