I might be buying a NAS in the future. I also might be upgrading to an i7-7700k when it comes out and using my current parts to build a NAS with FreeNAS installed instead of selling them. The NAS would have a i7-4930k, Asus P9X79 Pro motherboard, 32GB DDR3-1600 RAM, GTX 780 Ti, 850w power supply (not sure if it work because it fell on the tile floor), 2x6TB WD Green HDDs, 512GB SSD (if I upgrade to a bigger SSD on my main PC), CM690-II ATX case. If I get a stand-alone NAS instead, it will most likely be the QNAP TS-251+. A stand-alone NAS would be much less obtrusive than a giant tower PC and consume less power.
