Make sure it´s 3770K, not just 3770, or you´ll be struggling to overclock...
I´d avoid Sanforce Controlled SSDs, they may have issues. Samsung (830 or 840 PRO) comes widely recommended, they got their own controller, less issues. But, if I were to go with a Sanforce controlled SSD, the Intel 520 would be it, was my original choise... And with a new SSD on the fast SATA you can skip the RAID setup, you could measure a difference, yes, but I think you´ll be plenty satisfied with just one fast SSD.
How big is that cooler, will any high profile RAM fit under it in the first slot? I admit I don´t know that particular cooler...
