Portable GPU-cracker station
Am in need of a portable cracking machine I can bring with me on certain Internet-access restrained missions.

Used to have a shuttle barebone a decade ago. Loved it. Was thinking of getting a similar station with at least 2xPCI-e.

Anyone ever tested similar hardware? What would your considerations be?
BitFenix makes some nice small cases that can house midline GPU's.

Also, check out Tek Syndicate builds. They do micro gaming machines that should suit your needs.
