Hello all, King stopping in to grace the spot. Hoping to have some good knowledge and general tips while here. I currently own a PS3 and Xbox360 and both are broke (cheap parts cause problems) The laser on both systems are gone and they are past warranty. So I will be fixing them myself. I want to upgrade the PS3 from 40GB to 60GB and wanted to know if everything( motherboard, laser, hard drive) will need to be replaced to have backwards compatibility.
