...but a bit of black/charcoal paint would make it less of an eyesore.
To my knowledge you'll get functionally a stock A1200 with one of these - yes, a CD32 compatible keyboard could be hard to find...

Further upgrades aren't likely. Still my CD32 is my most heavily used 'real' Amiga - The A1200's are almost permanently in bits as the objects of my eternal fiddling.
