This is what would IMO be an awesome project and you could make a lot of $$$ if you tried to do it:
* A1200D case (slightly larger than original, but still keeping the same old feel and style)
* Slot for a CD drive
* Slot for a Floppy drive
* Bracket for mounting either a 2.5" or 3.5" hard drive
* Room and cooling conditions for BlizzardPPC & BvisionPPC
* Extra hole(s) for a VGA out and FF/SD out ports
* Dedicated area for mounting cooling fans
Think of the possibilities! 8-)
