Look, if you were looking to have more options handed to you, you are in the right place!
TrueNAS is a great diy option. I have it running on an old box of mine. The one real caveat is that you will need enough hard drive slots (don’t just hang them unless you go full SSD), 4+ SATA ports or add in a SAS card, enough PSU to handle all your drives, and enough memory.
I am running one SAS card and 16 GB of DDR 3. Since the attached image I have taken pics of the serial numbers and labeled the drives.














Hah, if you are near Cincinnati, I have a system with 6 SATA ports I just rebuilt for $30.
