Yes I realize that thanks, just wondered if there was some new product combo out 
there for existing towers, i.e. dual power supplies with controller boards, 
from your comment I assume there is not.

I'd be willing to migrate all of my hardware, i.e. motherboard, monitor card etc,
to a new case, if I could find a case which includes a controller card for the power supplies, or
a case that comes complete with such.  

> I'm curious - why does your desktop needs so much redundancy ?

Because I use the desktop machines about ten hours a day, I work out of home, 
doing graphic design, web design, uploading files to server, managing server, etc.  The home
desktop machines are just as mission critical as the server I upload to is.  Maybe more so,
because if there is a problem server side, I need remote access to it 24/7.
