Okay, you have my interest. I assumed you sacrificed the graphics
card slots for the additional CPU and memory. Pray tell the order.
I'm running a 3540 with the second box kept as running spares less
the processors and memory.
At one time, after one beer too many, I had thoughts of repopulating
my second box to a 3540 level and building a M-buss extender to come
up with a 3580. However, the hangover and the light of day squashed
those thoughts :-))
