Although, if you already have a system built it doesn't seem like it would be that much more of a PITA to just take that than it would to try and put it all in a microATX case that is probably only marginally smaller, unless you have a full tower setup or some special reason why it can't travel.
It's definitely probably cheaper to simply do the microATX thing if you already have most of the parts than it would be to buy a laptop that has any kind of decent gaming capability.
