Thinking about getting external GPU for my Vaio Z.

http://www.techradar.com/news/computing-components/graphics-cards/how-to-make-an-external-laptop-graphics-adaptor-915616 I'm thinking about getting an external GPU for my Vaio Z. The reason? Well, the Vaio Z has Geforce GT330, but I can't program CUDA on the good laptop. :( So, I'm thinking about getting the solution on the link above, when I have enough cash. Well, it actually isn't a very pretty solution...
