The SE/30 board will certainly *fit* in the dual-floppy case, they're the same.
The problem will be with getting dual 1.44MB floppies working on the SE/30. There's only one internal floppy port on the SE/30 motherboard. You could probably solder a flexcable onto the pads for the external floppy port with an internal floppy header on the other end, but wow, that'd be a lot of work...
