Everything should fit, though a few suggestions.
- Cheaper board = http://www.newegg.com/Product/Product.aspx?Item=N82E16813157312&Tpk=asrock%20z77
- You're getting a z77 board, might as well get the unlocked(K) version of the i7.
- Might want low profile RAM, but the RipjawsX should be fine.
- Scrap out the PSU completely. CM PSUs are known to have high failure rates and arguably mediocre performance. 850w is also overkill especially for a single GPU unit. Get 500-550w instead.http://www.newegg.com/Product/Product.aspx?Item=N82E16817207013
