Hello,
Has anyone ever tried to take a desktop PC anywhere on a train with any degree of success? I don't really want to buy anything special to carry it in, think I'd be able to get it into a suitcase without killing it or myself?
stick it in a suit case and pad it with colts towels etc, and be gentle when carrying and try to lay it so the mother board is on the ground side. and not hanging with the cpu cooler, gfx etc pulling on it.
Presumably you're just talking about the case with its internals and not the whole kit (keyboard monitor etc).
Ideally I'd use the box the case came in if its not too big.doesn't draw attention to the fact its a PC and has the internal packaging intact. Otherwise the suitcase and towel idea is a good one - some bubble wrap would be good if you have it too.
I'd also sit in a seat that meant you could keep an eye on it if its in the luggage rack.
