Glad to.

You'd need to cut some holes for the fan and the new port locations (which
add ADB).  Also, the metal chassis is different.

SE/30s have SuperDrives, the Plus doesn't.
The video circutry is completely different.
The keyboard is ADB, not direct.
The power supply is new.

True, but you'd need to get a power supply and analog board as well.
Not to mention a display tube from an SE (the signals won't drive
a generic monitor).

Also, you'll have to find an SE logic board to send back since the
upgrade cost includes the rebate for returning the old board.
