Well, it's not *that* bad. There is a tiny sort of hook-over thing at 3 (?)
places along the bottom of the front, under where the keyboard is
supposed to sit. Not that I can draw, but from the side it would look
something like this:

		  metal	-> || <- plastic
		   pan  -> // <- cover

What we generally do is to undo all the screws, then stick a
screwdriver between the metal bottom pan and the plastic cover, and
lever the plastic out until it pops off the metal. Then move the
screwdriver along and repeat the process as necessary. You don't need
to pop the plastic out very far, and it's fairly bendy.

No, you can't. This project did exist, but it got cancelled, hence the
misleading mentions in some of the catalogues. The FPU chip and
associated hardware would have sat on an expansion board, taking up
one slot.
