i would like to get a sawtooth or giga bit mobo into a blue and white. I love the case but would like a faster processor. I have 700 mhz zif but the bus is now 66 mhz. I think the power supply will work if i use the sawtooth or gigbit board. This would allow me to use the memory and hard drives. Does anyone know if the back plane can be changed to accept the i/o ports from the new mobo. Is it possible to use the newer apple cpu (quicksilver) in the old board?
