Portable ITX case?

Hey guys. I'm looking for a case that can be easily transported like in a plane. Note that I'm not going to be using any aftermarket cooling solutions.

Do you need a GPU?
If not there are lots of cases.
-Fractal Node
-Silverstone RVZ01
-Silverstone RVZ02 (Unreleased I think)

If you don't need a GPU there are really tiny cases but most have external PSUs so take that into consideration.

I am going to be using a gpu.

This.

Silverstone SG-13B/Q?

I reckon you can fit that on a plane without too much complaining. Just make sure it is a carry on, not baggage.

This is my nomination. Small, very powerful, very reliable (Server grade components), very badass looking...

Modify as needed ;)

The Elite 110 is probably what you're going to want, though it's too bad the fury nano isn't out yet

Although you could go with a GPUless build with an APU and some 2400mhz RAM if you were feeling crazy, but that would be even smaller.

Although are you building a new rig just for the task? Because why not just get a laptop?

And if building a new rig did you have a budget in mind?
