I might would check out the Extreme4 from ASRock. it has the features like you want for less and is obviously one of the best selling boards on newegg.. its sold out. Ah also the Fal1ty from ASRock is a considerable option
ASRock is a subsidy of ASUS that makes budget boards. Fewer features, but better actual boards at low price points such as that.
For that price point, I'd get the Gigabyte z77x-ud3h as my first choice and the ASRock Extreme 4 as my second.
Don't use an H50. A closed-loop water-cooler will be MILES worse than an air cooler. They're noisier, less efficient, more prone to breaking, and almost guaranteed to hurt your system when they do break.
Get a Hyper 212+ or EVO. They cool as well as that POS, and do it quieter, while being easier on your wallet.
