I am not sure about the floppy drive other than the caps may be an issue on the motherboard. I dont remember you mentioning if thats been done. LCDs are an easy addition. The video adapters from DB15 to VGA are still pretty easy to find. I get my 15 inch LCD's at Goodwill for a dollar or 2 (distribution center by weight) and so far I have not found one that doesnt work with my older machines.
