Does anyone know of one? I have several rackmount computers at work that require at least 5 amps on the -12V rail. I got one computer to work this week by adding a second modded PSU. I added the second PSU so that it's +12V is wired to ground from the the main PSU... and used the ground from the second PSU as -12V (good for 6 amps). But I had to take the second PSU apart and isolate it's circuit board ground from the case.

Tough call. Most only have < 1A. 
Yeah I need six more PSUs but I don't want to mod them. I'll probably buy some good single output 12V supplies and wire a relay so the MOBO can control it.
BTW, construction quality of the $25 PSU I modded was horrible! The soldering looked like something I did when I was 9 years old. I removed all of the wires except PSON* and two each +12 and Gnd which made it look a little better.
