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
