hello again guys, its been a while since i opened this forum regarding the Intel Imac powering issue.. i have managed to get hold of this another intel imac which is 17".. i will be collecting this imac sometime later today. this imac has a faulty screen.. the reason I am buying this is so i can exchange the power supllies so that my 20" intel imac can come back to life.. 

do you guys think this method would work even though the one i am getting today is 17" and the one i wana bring back to life is 20" .. see the images of the 17" attached to this post please .. would the 17" have the same kind of power supply and also is it the same model imac as mine?
