All I want to know about this is what the pinout of the connector is. I want to know how it was done and the limits of what it can do. The author has provided very little information about it[0], which makes me a little suspicious.
Yeah I want to know that too - I'm not so much suspicious, he's obviously done something amazing - more I wonder if he really has 12 pcie buses and they are they really wired in a way that they can be hooked up in 4 different orientations? (and what is the signal integrity like?)
