So, I've had my 2011 15" MPB for a few months now and as such, have put a little wear on it. At one point, I had put my MPB in a backpack to move into another room and accidentally dropped the backpack a little harder than normal onto the floor. This caused a slight impaction on the right side as well as a strange scratch to form right around the same area. No damage was done to the hardware or the computer itself. I opened it up, looked around, and everything was fine.
