Start by shopping around at old junk stores. I do 1-2-3 mods a year depending. Start by viewing ANYTHING you see as a possible base for a build. My favs are taking OLD XT boxes or recognizable Pent 2-3 boxes and putting screamer hardware in em. They usually sell quick! You better have a LOT of patience though. Things never fit... and ya need to be inventive. Thinking about doing one in a picnic cooler this summer.... Check the links for peeps that have gone over the top
