Sorry, that doesn't work either: *everything* new seems to need a lot more
power than the older stuff. Certainly, last time I upgraded my own system,
I had to buy one that was 150% the power of the old one.

We already repurpose. There's a limit to parts - when something gets
surplussed, it has to have pretty much what we bought it with (a different
h/d's no big deal, though). And the budget won't *allow* say, 20 or 50 or
70 new servers in one year. I can give you, with a 98% confidence level,
that our budget (we're not DoD) will *NOT* be upped by 10%.
The sob's just "saved money" by a) taking away our water coolers (we can
use the metal water fountains, y'know) and b) not refilling one of the
three soap dispensers in the men's room on this floor. Mind-bogglingly
petty? Damn straight. Cheap? Bet *their* offices still have the water....
