the 100 MHz FSB.  The increase that you would see from 800 MHz to 866 or
933 MHz would be marginal, but so is the cost.  Get the what you can
with the money you have (after other expenses.

You should see the required (and recommended) memory listing that
Supermicro has.

I'm not an expert on any of these, all I can say is don't skimp on the
network.  Many clusters are built around the network (like ours) since
many applications are very bandwidth/latency sensitive.  Try talking to
network tech support and seeing what motherboards, etc. they recommend. 
I doubt they'll have any problems with the 370DLE, but it's best to
check.
