Subject says it all. Mac forums cannot figure out how to make it work, nobody has done it yet. One guy made his g4 into a touch screen, but nobody has nor can figure out how to put a mac mini inside the g4. Please show us the ways of the Jedi.

i can actually help you a bit in this department, theres a japanese dude that figured out the pinouts of the g4 imac's LVDS connector coming out of the LCD. you figure that out yout can solder on a DVI plug and plug it into the mac mini board. then, you need to find a way to fit the mac mini in the base of the imac. get an adaptor to inteface the fullsize dvd drive in the imac with that of the mac mini, and then if you want perfect seamlessness, youll need to solder wires to the rear panel ports on the imac so you can plug it into the mac mini inside. its a complicated project but if youre up for it you can do it. i wouldnt do it as your first electronics project though.
