ill suggest just buy a good lan case. That would be fine. CM storm stryker and CM storm trooper both are very good cases. Check out NZXT vulcan too....
I already have a case. My case is a nzxt h440.
Or, a $5 suitcase from Goodwill. The PC, and fill the rest of the space with clothes that need to be washed.
good idea lol
If its really a problem, buy a case with a handle on top.
Other wise, My prefered transport is to put the case in the back seat of a car, and seatbelt it in. screen on the floor, facing the seat. (IMHO belting it risks cracking the screen), and keyboard & mouse just beside the case.
well then the best option is to carry it in your car. use seat belt to fasten your case.....
