Saaya,

If you go to the Swiftech website and click the Liquid Cooling item, scroll all the way to the bottom and you will see discontinued products, it is under there. The reason it was discontinued is because the GTZ took it's place.

As for the 775 backplate, like you said, the holes just aren't high enough up to reach through for the screws. You might be able to bend the backplate enough to reach but in my opinion that would just put unneeded stress on the socket especially when you can buy the 1366 backplate and adapter from Swiftech for $10.
