Well reviewing this cooler was a real treat. My expectations for it were quite low, but after testing, my opinion of this thing is that it's a very decent solution. It's a poor-man's full cover block. More expensive than a GPU only block, but less than the EK or Swiftech full cover solutions. It's very restrictive, but there are higher end components for people who are overly concerned about flow rate.
It's certainly a unique product in the market though being an air and a water cooler. Check out the review here if you haven't already.
