That`s an interesting release. It covers older or mid range cards (generalization).
On the face of it, looking at it`s construction, it would do well to compete with one of the early HR03 models, although I wouldn`t put it up against one of the newer revisions.
It looks a good idea, as do the HR03(s), for any quiet htpc solution - with one reservation being the fins that go over the rear of the card and a pressumed bridge cooler, and possibly if u have a big-arse cpu cooler.
If it fits in tho, it would probably do a good job, if it`s cheaper than the HR03, and performs close to the earlier revs, it`ll be a good option. I have no doubt fitting a fan or 2 to it, although then making it non-silent, would improve it again.
