I’m new to this, and having a lot of fun.
I started with the Blackview MP80 running Ubuntu(Minecraft server on docker and Home Assistant in a VM)
Then I bought the BMAX for 82€ and moved HA on to it so I can wipe the MP80 and play around with Proxmox and Nextcloud erc without breaking my home automations.
Yesterday I got the Hardkernel H4+ with 16gb ram and 2x 6TB 2nd hand commercial grade HDD’s (testing them now, 3 month guarantee)
Looking forward to setting up ZFS pools for the first time, ans probably move my Nextcloud AIO over to the TrueNAS app
I started with something like what you have, and 8 years later I have an 18U cabinet that is completely full. Including 20 HDDs stuck all over the place with double-sided tape.
It’s a slippery slope
