[rescue] Ultra 20 PSU replaceable with PC PSU?

[velociraptor]

Anyone know if I can use a bog standard 24-pin PC PSU in an Ultra 20
M2?  I've got one at work that's making a teeth grating fan noise, and
I don't think I'll be able to convince the bosses to pony up a couple
of hundred for the Sun PSU.

I saw one report in the Sun.com forums, but was hoping for a more
reliable report from folks a little more known to me. :-)

Thanks--
