I only have a small shed so with limited storage all parts bikes are stripped of any and all usable parts, the parts are thrown in buckets, crates, and tubs till I find a use for them then I scrap what is left. (And drag home more from the scrapyard) I do always make it a point to take all bolts, bearings, bearing cups, seat posts and clamps, and anything else useful out before I scrap anything because they don't weigh hardly anything and are always useful to have on hand.
