Yup, I got my infinity fitted. There's a surprising ammount of room between my graphics card and the HR-05, and the HR-05 and the infinity. It all fits pretty well, apart from the mounting bracket. I'd be very curious to see closeups of your mounting bracket if you could post some, because I think thermalright are either just shoving random sized brackets in the boxes. There appears to be no logic behind some people being able to get them fitted to P5N-E's and others(I've read on other forums) not.
