these things seem incredibly conventional.  I was hoping for something 
a little creative, like heatpipes in the chassis, mating to a liquid-cooled
cold plate in the rack.  how about super-caps in the PSU to provide 
enough hold time to dispense with UPSs?  how about a distributed switching
fabric, like 6x10G port in each node, with an FR4 in-rack subnet.
something with dram stacked on an interposer with the cpu die?
