VERY STRONG RECOMMENDATION: DON'T buy Supermicro. They have a *lot* of
trouble with this new, fuzzy concept called "quality control".

For example, we have a cluster with 21 Penguin servers, about half with 48
cores, and the rest with 64 cores. You'd think this kind of hot, high end
server would call for a lot of attention.

No. We've sent back to Penguin at *least* 5 or 6, and a couple of those
went back *twice*, and almost all had m/b's replaced, and one a CPU, I
think. That's an absurdly high percentage....

Now, about what you're looking to build - you say that you want 1U, and
mention rackspace: in my experience, rackmounts are a *lot* larger than a
pizza box, so I'm a little confused at the requirements you're building
