Quoting StainMeNow
Man, just pull a Cyclonite. Build a rig for the specific purpose of carrying it onto a plane.
Hah. I didn't think anybody noticed. I won't be bringing it this year. I have a laptop that should support the minimal gaming I may do.
But it's definitely worth looking into a MicroATX setup. It worked out pretty well, and I was only stopped in security twice. They ran their little bomb-sniffer thingamajig over it and let me go.
//Edit: as a side note, Firefox doesn't think "thingamajig" is a misspelled word.
