The thing is, I have no idea what kind of troubles I may face at the airport. I am allowed to carry-on desktops, right? Will TSA agents give me crap throughout security? Will anyone protest that it's too big, too heavy, etc? Should I watch out for any computer parts that are easily susceptible to damage? I'm basically trying to anticipate any problems that may occur before they happen.
Knowing that I was bringing this pc to college, I bought one of the smallest cases I could find that still fit a full-sized graphics card. As so you can see in the images in below, it fits in my backpack, and that's how I plan to carry it (with some clothing for padding, of course).
So please, give me any advice you can. Thank you in advance!
P.S. I'm actually not sure if this should be in tech support, blog, or general (?).
