I had a bought an Ibook 700 at compusa about 2 weeks beore the new 800mhz models came out. So when they did come out I decided to make a few "burnt" pixles on the screen and royally screw it up so i could use the compusa warrenty I had and exchange it. But just to get my full moneys worth I tried to switch the board from my ibook 700 to my roomates ibook 600mhz model, no dice. The magnezium frame was completely different on each model, and even the screws that kept it together were somewhat different. So that was a no go, but we did switch the combo drives with no problem. And the next day i took the ibook 700 back and talked my way into getting thee new ibook 800, so it all came up roses. Hoped that helped
