Hi! I just built a new desktop gaming PC, and am now looking to build a gaming laptop. I have an old IBook G4 , and if I could change the motherboard and other parts on it, I think it would make a good candidate for upgrade. Plus it's got a good screen and optical drive already installed. Is there a motherboard I can fit into this case, as well as a good gaming GPU and processor? And if not, are there any cheap laptops recommended for upgrades of this sort? Thanks!
