About selling it: ask them to consider what happens if one goes down...
and "next day" service means someone shows up the next day (if you
convince the OEM that you need on-site support). That does *not* guarantee
that the server will be back up that next day (there was a Dell box that
we replaced the m/b three, the second one was dead, and they finally just
replaced the box because no one could figure out what was going wrong, but
that was two weeks or so).

*Then*, once it's up, you get to restore everything to production. Try a
tabletop exercise, as we have to do once a year, on what do we do with two
or three scenarios, and guesstimate time for each. That might scare
management into buying more hardware.

As long as they don't freeze your salary or lay someone off to pay for it....
