> The down side to the old enterprise servers is the power draw.
It depends on the generation of the gear. Stuff coming off-lease in the last 3 - 4 years has been of a generation where lower power draw became a major selling point. In Dell land, for example, the power draw differences are dramatic between the Rx10, Rx20, and newer series. (Basically, throw Rx10 servers in the trash. Rx20 servers are better but still not great.)
