Looking at the CPS1 multi, my existing CPS1 plates should fit. As i'm sure the holes will line up to be a direct drop-in replacement of the B board. So then I would just need to make a custom top plate for the LCD and controls. Is it the same as the F3 or the ST-V? How's the ribbon cable configured? (sorry, I'm sure all the answers are in the thread I just haven't been keeping up)
I hope so - I have your current CPS1 case, and it's great!
