Does anyone know if I can take the motherboard from a 1.42GHz eMac and put it inside a 1.00GHz eMac model? I am planning to pick up a 1.00GHz model on Sunday because its CRT is practically brand-new while my 1.42's has some burn-in and flyback transformer whine. It would be nice to just swap the boards and drives and call it a day, but I know that the heatsinks could potentially be different and I don't want the 1.42GHz G4 to overheat if its heatsink is bigger and won't fit inside the 1.0's shell.
