Yes iFixit is pretty much todays standard in every repair I do.I just upgraded my ibook hdd and your gonna be pretty much taking it down to the frame so if you ever wanted to do any thermal paste or ANYTHING else I would go ahead and knock it out.It really dont take that long and is really simple with the guide,I always trace my laptop on paper and circle where the screws I take out go since you take a lot of them out.The locations where the case snaps on is the worst parts but a good spludger makes it easy the ifixit guide makes it seem hard when the say "trying times ahead" and stuff like that.
