I am flying up to Kansas to visit the alma mater (rock chalk!) and am bringing up some computer parts to upgrade my sister's laptop. New hard drive and RAM. I'm assuming I should put these parts in my carry-on bag, because airlines do horrible things to checked bags. Are these parts okay to go through the X-ray machines and metal detectors in their own boxes not installed in a computer? Should I take them out of my bag when I go through security? I'd love to get anybody's opinion on this, I really don't want to wind up in Guantanamo just for having some parts for my sister. Thanks.
