I use FreeBSD+ZFS rather than FreeNAS, but it's the same idea. I store all of my photos and videos, all of my music, and all of my movies. The music and movies are served via Plex and Sonos to various parts of the house, and I use Lightroom to browse the photos. This is not the only copy of any of this stuff, though. The photos get synced to S3 and backed up on a second local hard drive. All of the movies I have are rips of DVDs and Blu-Rays I still own, and can use if needed. And my music is all in Apple Music/iTunes Match (and on my computer, backed up via both Time Machine and Crashplan). So, I'm using the server really as convenient local storage for stuff, not as an alternative to the cloud.
