Mike, the round ring you drew a circle around looks like the old Corsair mounting rings. They were a Pain to install. As I recall it was on the H50. You had to very loosely attach the round ring to the backplate then set the pump through the grooves in the ring and twist it to lock it into place. You needed to do this without the block touching the CPU because of the thermal paste. Once you did that you could screw it down. It was a real pain to do. That ring wouldn't be a backplate because it wouldn't need the grooves on the inside. If that is the way it fits on, I won't be getting one. Those things would make a Preacher curse.
That's as best as I can remember. I only bought 1.
