fukken Dell... how to remove vid card?

I need to remove my video card from my Dell XPS Gen 3 but it has this green plastic thing locking it in (instead of, oh, the usual way of just screwing the card in like normal).  How the shit do I unlock it so I can remove the card?

I figured it out and removed it.

Now I need to remove this faulty fan from my video card.  The fan device is hooked up via 3 small wires (white, black, red) but I don't know if the plug is disconnected on the fan module or on the video card.  Both seem to not want to budge at all.
