Well, I dragged it out from under the desk and popped the back off. Peering through the PSU's vents, it's now clear I _did_ replace the Y caps on the primary board with film caps, so I wasn't quite as sloppy as I thought I was.

I let it run for almost 1 hour while periodically sticking my nose in the PSU, and installed patch 1550 while I was at it to finally get my RE textport back. Lo and behold: didn't smell anything funny. That said, I ran it directly off the outlet rather than the power strip all the other crap is on.

So either the power strip and/or cable is dodgy (the extension does get pretty warm), or it's kicking up some crusty dust from under the desk. Maybe I should stick air fresheners inside?
