You should see these three A2000's that I just cleaned out. Came from a smoker's house. Had to replace the floppy drives on all of them except one with hacked PC ones. Had to blow them out, take the shells out in the sink and scour them with Comet, etc.
Watch out if you ever clean a badly smoked out PC. After cleaning one such PC, i actually had enough of the nicotine leach into my hands to make me ill.
