Can't pull up any files currently since my PC's are all hacked up today and I 
have some major file copying going on, but I used a TI/Unitrode UC2577 device 
in SEPIC mode for the 12V section.  I'm trying to remember the specs now, but 
IIRC I tested to 700+ mA output on the 12V line.  I've been able to run an 
internal CD-Rom drive properly off this PS, with the only other 12V devices 
being the fan.  I'll get you a schematic when the dust settles here.  BTW, I 
found some interesting devices using Linear's SwitcherCAD software recently, 
but I've been avoiding those SSOP-sized parts.

Cheers,
-Neil.
