This is how I removed the connectors.
Excellent description how-to do it.

You have to get a pre-heater. Aoyue 853+ or better at minimum. Don't use a super big soldering iron, you will just burn the vias before you remove the part.
Cut the back three prongs on the connector before you start. That way you are removing them one at a time, not six at once.
And the super magic secret: Tin the leads with lead/rosin solder. This will lower the melting point of the crap ROHS solder a lot and make removal easier.
Use very good flux. Flux cleans connections and transfers heat.
Once off, use the solder wick to take up all the solder. Flux is good.
Clean everything up before installing the new one.
Flux the ends of the new plug before inserting. That way the new solder will flow.
Heat the board again then solder the back three pins.
Flip the hot board over in your lap and solder the front three.
Oh wear thick pants.
Clean everything up and admire your work.

I have been really struggling trying to desolder mine as well. I burned the pcie connectors on mine just like in the picture above. By any chance do you have a video of how you removed the solder? How long should it take to remove the solder from a single hashboard? I worked one on for hours the other night and didn't even finish. It has been very difficult, to say the least to remove the solder. I will say, that I don't have a preheater though. Do you thin that's the critical step that I'm missing?
