All right here is my question maybe someone can answer this for me. My PB 12" bottom casing has a dent on the left side of it. (Don't ask what happened, as I'm very anal about my machines) I was wandering if I buy the bottom case will genius bar install it for me or do I need to order it from them. The reason I ask this question is I would do it myself but the serial number is on the casing. As If I replace it myself and then later down the road my HDD goes and they look at the s/n and it's missing..
