I'm testing FreeBSD right now and will test *SunOS before commiting a full
deployment.

My initial 3 nodes are socket 940 Opteron based.  I'm planning to acquire
two nodes of dual cpu hexacore Xeons for the cost of a small road trip next
weekend (otherwise free).

The more I think about it, maybe I'll have two clusters, one for Opterons
and one for Xeons.

I'm currently out of work on medical leave and don't have a lot of free
capital.
