That depends on who's paying for it. If your in-house support your screwed
of course, since all of them think your labor hours are inexhaustable.
But if the users are in a small business or whatever that has to actually
real money to have their systems updated, then they are usually a lot less
enthusiastic about new updates (at least, their owners are)

I do the mirroring thing too but the one thing you have to watch is
cooling in some of these minitowers. Stacking the disks on top of each
with no cooling fan blowing air on them is not a good idea.
