I bought this poor condition P54VL-PCI board for $20 on eBay (only bidder) and received it on Thursday with the broken VRM 3.3V fixed module (I have a spare on hand, thankfully).

The condition of the board was not really good as it looked like a mouse or something made a nest or something on the board at one time and there was so much gunk on the board that I deiced to do the cleaning process.

Photos of the board during the distilled white vinegar and 99.9% Isopropyl Alcohol bath (pouring, scrubbing, and so on):

There's a bit of crud on the underside and I'm not sure if that's rust or just old flux.

I archived the BIOS in case anyone is looking for the BIOS for this board: http://vogonsdrivers.com/getfile.php?fileid=1762&menustate=0

I also removed the NiCd Varta spewing of DooM from the board, however, that didn't leak at all or cause issues with oxidation/corrosion.
