If you leave them on, add up the power cost of running an old box for years.

Yes, if someone does the report to show that it will save money in the
big picture...  But you don't necessarily throw out the 3 year old
boxes, you can re-purpose them to something where people aren't

In any case, someone should be accounting for the space/power/cooling
that old hardware takes while accomplishing 10% as much as new.
