I want to use a smaller case because I move frequently and the Zalman
Z11 is a big case, I'm selling the case, gpu, mobo but don't know what
parts I should buy to replace them.

additional details

I want:

a very small case with a handle. A gpu that will fit in it and won't be worse than a GTX 760 A mobo that will fit in the case with 3 sata ports, pcie 16x

I also have 2 more questions: Is the 212 EVO cooler going to be a problem? Do I also have to replace the PSU?

I'm also not afraid of 2nd hand stuff.
