Huh! you guy's are keen! XD I actually have it working on my alienware 17, I'm getting PCI-e 3.0 with all 16 lanes, but only at 2.5GT/s so I'm only getting 4.923 GB/s over the link, which is still better than pci-e 1.1 though, which is at 4 GB/s.
I am working on a better prototype at the moment, as soon as I hit the PCI-e 3.0 at 5GT/s or 8GT/s I'll be starting my kick starter, It's taking some time because I don't have income at the moment so if you guy's still want to make your own go for it it is possible!
