90watts 24/7/365 at 11 cent a unit (lets say you have such a deal)
=607 euros in euros or thereabouts - if it is running at 85 percent of
max power it is still over 500
now lets work a cheaper new box with costing about 350
running 14 watts 24/7/365 (and kernels with wake on lan make this number
lower) = 94 euros in power or thereabouts
you could have two of the cheaper boxes running (failover if you really
needed it) and payback is less than 1.25 years
ohh while you are at it look at the cost of getting a good kernel that
does power scaling on a bigger more modern box (like the one Tim is
pointing at) and pay more to get better scaling and all of a sudden you
have different calculations and a "hardier box" to work with
the brick .. well that would be running at about 25 watts it will be a
little lower than the PSU can deal with ...
have fun thinking about the arithmetic if you do get lower power boxes :)
key questions as asked earlier, what is the function, and how sustained
