that is a great motherboard, but socket AM3+ is for AMD processors. for your i7, you want socket LGA 1155. this is one of the top boards within the same price range:http://www.newegg.com/Product/Product.aspx?Item=N82E16813157263
Also, are you using this PC mainly for gaming? if so an i5 2500k will suffice. the i7 does not offer any additional advantages for games, but it does for heavily threaded tasks such as rendering in adobe software of maya.
the cooler master haf series has a great reputation for cooling, so it's a good choice
as for your ram, it's reusable, but those ram sticks are pretty slow for your shiny new set up, and ram isn't that expensive now a days. something like these would be a great investmenthttp://www.newegg.com/Product/Product.aspx?Item=N82E16820231428
