Anyone ever tried to mod you macbook? I mean not just adding a little piece of coloured paper behind the apple log to change it's colour... I was wondering for ventilation mods, video card upgrades. I would love to see a vent mod. Better cooling just for the funzzies. Anyone ever found something interesting? Like water cooling or something? Btw, I was wondering, does the back cover of a retina display macbook pro (I guess 15 inch?) go on the back of an normal macbook pro early 2011 15 inch?
