Modifying PCIe x8 to x16

Just get a Dremel-like tool and chop the end of the connector off. Works perfectly. Be careful to not mess up any of the pins or cut traces on the PCB.

This is Dell PowerEdge R610, and it only has x8 slot with the end closed. The riser is only worth $14 so you can mess up couple of times and it will still be fine.
