We just purchased ~150 dual AMDs, and are cooling them with 4 Fujitsu
ceiling-mounted air-conditioners: about 50kW of AC cost us about $25k,
which is about 10% of the cost of the machines.

So yeah, you're getting screwed.  It might be that your facilites people
are thinking that you need one huge monolithic cooling system, and you
may; however, cooling in a piecemeal way ends up costing a lot less.
