Go for the H77M - been using one for over 6 months with no problems (saves a few pennies as well). Price a WD 1Tb Blue as its got 64mb cache (or black with pennies you saved on MOBO) and isnt sluggish!
Thanks for the input. I've heard it was a really good board, but I never owned an ASRock mobo. That was my first pick based on reviews.
Also thanks for pointing out the HDD, updated to the WB Blue for only $5 more
