that icy box thing looks cool. I have been looking for something like that for a while, trying without luck to use some other non-backplane devices that haven't fit properly in the case, or have pieces broken off after very light use.

As for the other comments about environmental friendliness, well it's not that bad. Running old enterprise gear will more than likely use a lot of power. The processor and power supply in that build are a bit overkill, but I think it is overall ok. You could get a 45W version of the processor and I bet that power supply won't be using more than 10% of its capacity, so yes it might have efficiency issues. 80Plus certification only measures efficiency at certain loads, 20% being the lowest, so who knows how efficient that will be at 10%. But of course you could add a GPU in there, or run a few virtual machines. I still don't think Atom's are worth it for general computing, as the platform is pretty limited in terms of expansion (no PCI, seriously limited RAM).
