When I went to take the cover off mine, i discovered that there are 3 ridges
that catch when you try to lift the top off.  These are on the inside of
the plastic cover, just under where the keyboard sits.

                 |    <<monitor above here>>   |
<<keyboard here>>|                             |
   ---------------                             |  fan blows out here
  | <- ridges on this surface                  |
  |                                            |
 

If you take a pocket knife and carve those ridges off, the cover will be
LOTS easier to get off next time.  The first time I took the cover off, I
had a lot of trouble trying to 1) lift the cover with attached monitor,
while also 2) trying to pry all three of these ridges away from the metal
case.  Scraping them away doesn't make the cover any less secure.

If you are savvy about such things, you might want to change your floppy
drive for either a 3.5" drive or a 96 tpi drive.  You can then make 800K
disks instead of 400K disks.

I took my floppy drive out of the cabinet and installed longer cables for
it.  I ran the cables out through where the left fan would have been.  To
this day, I have a 48 tpi and a 96 tpi drive sitting next to my machine
waiting for "one of these days" when they will get mounted in a real box.
I swap them back and forth, using the 48tpi drive for compatibility (e.g.
distribution disks, msdos files) and the 96 tpi drive for everything else.

Have fun.
