Yes, that can be done, but there are some issues... aka the psu must have some basic values for the lines, and finding one suitable can be a problem. Plus if I remember right you need to have the connector (in my case I don't have it), to swap it and tweak the cables (with the hope of not doing an error in the meanwhile). The other issue (that at least applies to my case) is not being 100% sure that there were no damages to the boards caused by the busted psu

The Fuel PS can be swapped for its PC counter part. Wonder over to Nekochan.net and search for Fuel Power supply, there is a lot of info on this. The p1 connector has to be resorted and the replacement PS has to have the fan monitoring and that signal has to be adjusted to what L1 expects. The motherboard has several environment monitoring ICs that, on the early revisions, go bad and keeps the computer from starting. These ICs are/were available for the brave hearted to attempt the repair. The later motherboards apparently don't suffer from the enviro monitoring failures as often. Nekochan is a great resource, it was invaluable for me when I was building my Fuel.
