If you're willing to dremel out the grill then the UK on the case wall is a better setup than on the farthest mounting point.
I'm halfway through modding it right now, but I've been too busy with school.
I'll be cutting out the PSU grill for sure, and I'll give some thought to the rear grill as well. Maybe even making the whole big enough that I can mount the H50 externally
And the rear grill on the CM690 is fairly restrictive, the way the air moves through it causes the noise. It happens with every fan I own, which is why I've taken to using a shroud to separate it.
