I bought the rear backplane for the dual 2.5 inch drives in the back. Going to throw the boot OS on it so I don’t have to worry about a USB drive dying or becoming corrupted. Good luck on your journey. Really interested to hear how it goes.

Ooof you have me worried. My R720XD shipped out yesterday and is supposed to arrive Monday. My plan was to install TruNAS Scale on it to replace my old tower with unraid installed on it. I have roughly 25 docker containers that I run. What kind of errors did you see? It’s scheduled to be installed in the data center week after next so I don’t have a bunch of time to troubleshoot.
