We need to take a smallish (22.5" x 10.25" x 12") desktop computer (Silverstone Sugo SG04) to a tradeshow. I think carry-on is the best option. The computer has a traditional HD and an SSD. Is it okay to put it through the x-ray machine? Does TSA allow a computer which is not a laptop and has no monitor to be carried through without the x-ray. Thanks.
