What do you mean, saving money is not at the top?
We mean that the cost "saving" of buying an expensive new "energy efficient" server as opposed to keeping the existing one running doesn't appear to exist in a lot of cases when you look at it with the degree of scepticism that people subjected to con artists/sales droids on a regular basis do.
Scrap your existing (in warranty) hardware and buy our new "energy efficient" server! (for £5k+) Its so much more efficient (per watt, but it draws more in absolute terms than our existing equipment) that it could save you thousands on electricity costs (over 25 years, which is 5 times more than the maximum warranty period)
