1. The only difference between the cases of an SE with a hard-drive and one without a hard drive was a removable piece of plastic covering the upper floppy drive slot (and maybe some print on the front of the case and rear label).
2. It should support dual internal 1.44 MB floppy drives if it has support for 1.44 MB floppy drives. (Any SE mother board can do so if you replace one chip (the SWIM?) and the two ROMs.)
3. Yes. AFAIK, the power supplies are identical (though I can be wrong).
