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

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

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