This is getting OT and you are going to end up spending more on redundancy then if you just called Dell and ordered another computer.

So for a top quality power supply for a mission critical desktop machine, which
brand(s) would you reccomend?  One of the towers I have is a Thermaltake 
Xaser 3 with lots of room, and I just bought a new Antec Sonata III tower
with a 500 watt PS.

Then for a Mission critical desktop machine, if you had to make
a choice, would you go with a good quality UPS and/or redundant
power supplies, or a BBU instead?

As an alternative to RAID1 for a mission critical desktop machine @
home, what would you reccomend?  Maybe a bare metal restore solution
able to restore to different hardware, (i.e. if a motherboard dies and drive
crashes due to power spike or some catastrophe,  I'm screwed
if I can't find the exact same make - model)?
