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,
