gigabit switches

Steven,

   Since the most likely dual Athlon board already has
dual 100Mbit  NICs onboard, why not get a low cost
100Mbit switch? (e.g. HP Procurve). It will have a decent
backplane bandwidth (possibly better than a hierarchical
network). I think the price will be as good or better (just
a guess though).

Good Luck!

Jeff
