At present my plan looks like a Synology DS412+ (or possibly an Asus AsusTOR AS-604T, or tThecus n4800) and 4x WD 3TB Red drives.
What other thoughts would people have to put out there?
(bearing in mind I have exactly zero interest in building my own)
Also, wasn't sure which forum to put this in, looked like more discussion on NAS in here so I went with that. If moderators have a better idea...
