[Scrypt mining] More than 4 GPUs on same PC

[Lionel]

How can i plug more than 4 graphics cards on the same PC?

I was wondering if some PCI Express 3.0 over USB adapter exists, so we can have even 15 Radeons plugged in via USB
For mining should be ok even if the bandwidth between GPU and RAM would be slow, because it does not count for this task.

I could not find such adapters, someone knows of them?

You can go up to 7 GPU per pc.

Things you will need:
1) motherboard that have at least 7 PCI-E (16x, 4x and 1x)
2) 1x to 16x PCI-E extender cable.
3) 16x to 16x PCI-E extender cable.
4) Custom casing.

Tata, you got a heater..
