Excellent cooling solution. Its so hard to find a cheap mounting plate so this is the best I could find. Bought 2 of them for my media server cabinet. I replaced the filter bars with cheap ones from ebay that keep out dust. Fans are very quiet and move decent amount of air. Looks very professional when built into cabinets. USB cords aren't too long so I needed an extender, but nice to be able to plug 2 of them together to save USB port.
If you need thermal control I would recommend this kit and adding a 4 pack of fans yourself here
This is what it looks like as finished product on my media center
