Use RPi for NAS is really a stretch. Just buy those low-power x86 mini-itx boards with 4GB memory and 4 SATA ports along with gigabit ethernet, they're around $150?
Note the smaller size of RPi-etc makes no sense when you're going to host 4 hard drives anyways which takes quite some space on their own, and you need a decent PSU for the drives too, and a solid case as well, etc.
Just buy those ASRock mini-itx boards at newsegg or somewhere and let RPi do what it's best at.
