Semi-off Topic:
I was at LinuxWorld yesterday oogling all the 1U rackmount cluster systems
there, and all that they could fit into them. It was almost funny how the
tried
and true classiccmp method of mounting the planar components pointing up,
so the heat "falls up and off" kinda got lost.
All but one of the 1 and 2U rackmount system sellers had their boards
mounted
horizontally, trapping the heat, and they had to compensate by mounting tiny
overworked fans all over the place to compensate.
Hilarious in a way, and I imagine if we look back in 5 years this will all
be different.
