There is a company that sells a case that will put 3 nodes in 1U. That is
the most dense I have seen. Of course, you have to buy from them (including
their mainboard, I think) and I have doubts about cooling in those things.
We're building 264 nodes (528 cpus) using 2U cases. A "standard" rack is 42U.
There is no wasted space, but you need to think about network switches, UPSs,
console management hubs, etc. which will take more space. I think we're
planning on 16 racks.
You can also get 1/2 depth cases that let you populate the back of the rack.
I'm not sure I'd want to deal the resulting rat's nest. Might be a way to
get the auxilliary stuff out the way though.
Good luck, and let us know how it turns out.
