Yes, I do have good spec's, see my original posting, although might consider
AMD as well. Joe, can you provide a quote?

Air conditioning problem has been solved, will put my new cluster in a
proper place with enough power and BTUs to dissipate.

Yes, will consider IPMI as people advise.

Would 5100 chipset work with 5400 Harpertown xeons?

Yes, except of IPMI as people advised.

Yes, this is what I am doing after getting this excellent feedback from all

We usually manage the clusters ourselves because don't have a resources in
academia for expensive support contracts beyond standard 3 year hardware

Yes, agreed. Would like to get this feedback from people in academia, what
things they wish have done if looking in the past.
