Are these common at all? I have mainly come across external chassis' that you then put an internal video card into.
All I want to do is buy a nice, sleek, thin, ultra book with some power to do my graphic design, video editing, some very minor 3D, photo editing and music on. I know I can easily get external audio interfaces (professional sound cards) through USB and/or firewire. I just wanted to know if there's a video option for times in the office or at home where I want it hooked up to do some media work. Yet, it would still get plenty of use without the external card when I simply need a portable laptop for minor stuff.
My ideal solution would be to have an ultra book and an external GPU that's enclosed in a solid case like an external drive.
