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 :-))
