I am looking for an ATX sized case for someone who will be carrying it fairly often. He took his computer on a bus recently and when he reached destination there was a bowl sized dent in the case and since christmas is comming i would like to surprise him with something that wont dent like that. I was looking maybe at the nzxt s340 for its full steel construction but its a bit on the high end of my budget (100CAD aproximatly). Dont care if its pretty it just needs to be built like a tank and be fairly portable.
