ProTip for those of you with QNAP devices - enable raid bitmapping. I had a TS-879 full of 2TB drives blow up on me (iSCSI firmware in it shit the bed, still not sure why) and it took almost three full days to rebuild without it. It's non-destructive, so you don't need to reformat to do it.
As far as a media server, I also run Plex and I use a Mac Mini for the head. 8GB of RAM and an SSD and I just mount it up via NFS to my home SAN. Works great, streams no prob. Plex is the goods.
