Personally, I'd skip the floppy drives since those are still cheap and plentiful. I want to say the same manual inject drive (not necessarily the same model number, but a compatible version) was used all the way up to the Beige G3s so there are plenty of machines to use for replacements. SCSI CD-ROMs seem to be getting a little bit thinner on the ground so if they're working and you have the space, might not be a bad idea to save those. I'd be surprised if the hard drives are still working if we're talking about machines that were in storage and not in active use since they're almost certainly Quantums. RAM from both machines is still available for sale and reasonably cheap, but if any of the machines has a high amount installed, again it wouldn't be a bad idea to save that. Apart from those things, and any interesting add on cards (if they have them) not really anything special/worthwhile to save.
