Are there any cases in the world that are sub 6 inches that are capable of holding a full size gpu that are slim mATX. The best size would be something in the are of an xbox 360. I am really looking for portability.
you can get short GTX970's ... so yes you can get a fair bit of power. coolermaster 120 and the prodigy M are as small as is practical. Prodigy is great.
I doubt that you can find a strong graphics card in such a small package.
Look at the lian li TU200.
It is light, made of aluminum with a handle.
It can hold the strongest of graphics cards. http://www.newegg.com/Product/Product.aspx?Item=N82E16811112348
