If you dont want the hassle, there are basically only two choices on the Consumer NAS market.
Synology, and you should also look for and ONLY buy models which support Btrfs. Silent file corruption is very real.
Personally I am waiting for Qnap's Hero Edition OS, because I just love ZFS.
Other than these two, I am not aware of any other consumer NAS which support either of these file system.
Or may be someday Blackblaze decide to enter NAS market :D
