WOW awesome find. Little bit of advice when tearing down the old systems. there is better then scrap value in a couple of the parts for sure. The 5.25 flppy drives seem to sell pretty well on ebay. Even untested I have sold 1 for $15 and one for $20 just this month. Also the 5.25 and 3.5 floppy drive combo drives sell well too.
