Help with radiator identification, alleged Hardwarelabs BI Nemesis

Hello everybody,

I hope someone of you can help me, I recently got hold of a supposed Hardwarelabs Black Ice Nemesis GTX 480. I’m pretty sure it’s NOT a Nemesis GTX 480, let alone any Hardwarelabs radiator.

I have three pictures here, can someone tell me what they really are? If I remove one of the plastic latches I can see a simple antechamber behind it, not layering like the Nemesis GTX would.
The processing quality of the thing is otherwise quite good, right down to the small protective plates under the screw holes to protect the radiator.
But FPI are very low, 9 or so if I haven’t measured myself. Thickness is 6cm on the side shield, down to the fins are 5mm each, so the fin stack is 5cm thick.
