Regrettably not. I'm part way through modifying my PowerBook's IDE cable to fit in the chassis with an IDE -> SATA adapter attached. I would have used a heat gun to do it, but it's most probable the flex cable would melt, so I have to individually desolder each of the 44 pins, and relocate them. I don't expect it to be done any time soon!
Do you expect it to be done any time soon now?
