I was going to call you lucky for be able to get such early access to the Dark Rock 3 series, but I see that, for us Americans, NCIX has started to carry it as well! Brilliant!
Either way, I think overall you be quite happy. I obtained a Shadow Rock 2 not too long ago, and it's a stalwart piece of equipment. My only complaint is that the installation is a bit trickier than your average CPU cooler to install. I also didn't like how Be Quiet! only had one set of fan clips for the cooler, but they sent me an additional pair after I had contacted them about it. (Straight from Germany! Took about a week and a half.) Even though their products are a bit on the more expensive side, they seriously are very well made.
