I'm helping put together a rack-mounted cluster (around 30 nodes) and
came up with the following hardware. This is largely for
compute-bound scientific applications. I'd appreciate your comments,
recommendations, and criticism on it. Higher bandwidth/lower latency
interconnect is not economically feasible at the moment.

Thanks in advance,
Denby

I hope you are paying no more than $20 for the rack. That's
a way over the top price for a good one secondhand. DEC racks
with power controller can be had for about $5 on a good day.

What would economically feasible when it comes to an interconnect?
Have you looked at the WulfKit solution from www.dolphinics.com?

absolute best setup, even down to the switch. 48 ports 10/100 with
2gbic's and it's 1u. of course, with the faster athlon's out, i'd opt for
them.
