That was just a quick build and its still roughly R3000 less than the Rig in the article, and its by far superior.
Drop the 3D vision, its useless and just a fad, that the end user will drop it within a week.
If I was seriously gonna build the above mentioned rig I could probably pull it off for around R22 000.
