Well honestly if you're not planing on using SLI you can just go for something cheaper but same quality:

But the one you picked is great board.
As for the cooler, I don't know that one so I'm not ready to recommend it to you. The best at that price range are these ones:

Some even allow to add a second fan on them for more airflow. These are all just variations of each other, with quieter but lower RPM or the louder with better RPM. Definitely doesn't look as nice as the one you picked but at least we know they're reliable.
