My son (17 at the time) is a computer tech and his personal laptop has all kinds of mods on it, including missing pieces of the case trim so it is easier to swap out the hard drive. He did get questioned at YOW about it but when he showed them he was carrying a second hard drive and the mod was to make swapping easier, he was let through. This was after Aug. 10. On the return trip, YHZ didn't even notice.
