I'm looking forward to see the write up for the installation and what you did luchazo. I am going to attempt a very similar build with a EVGA 780 classified and perhaps the Xeon E5-1650 v3. The case I want to use is one that is not out already, but it is a beautiful small form factor made by a user in hardforums.com. The case is called the DAN A4 (http://hardforum.com/showthread.php?t=1799326)
Anyway, look forward to hearing your progress with the Cube!
