Hi, I am the proud new owner of a core i5 MBP! I am loving it a lot so far, but I have noticed something a bit odd... every once in a while I hear a little clicking noise inside the computer, when I'm moving it and when it is sitting still. The sound is for sure coming from inside the computer. Could this be something wrong with the inside? It's not a gigantic problem, just a minor annoyance and I want to make sure that nothing is wrong!
