Need some help picking G5 motherboard (and other parts)

I know it's been done a lot but I just want to see what you guys think is the best option for me. I'm looking for a motherboard that will fit in an old G5 mac, and before anyone says "why?" or "just buy a modded one", that would kinda ruin the build for me and because I found this sucker while cleaning up a homeless encampment (I work for the city I live in) and so I want to give this puppy some new life. I was just looking at motherboards and wanted to get your guy's opinion. I was also gonna try to find as many parts as I could on eBay that are used just so that way it fits with the theme of giving new life to old parts :) any help is appreciated!!
