If you think the price is high, I would point out that the SSD I used cost €200 new when I purchased it back in mid 2022. A used 120 GB SSD by contrast can be had for maybe €10 which alone would explain the difference in cost.
Now if 120 GB is enough for your application, that's a good value so more power to you.
Thank you for the links, that morefine one seems really nice, would need to get 2.5Gb networking gear...
I currently have a single 16 core/64 GB ECC Ryzen tower with ZFS that I'd like to break into a ZFS ARM ECC NFS server with a separate small form factor Ryzen or ARM compute cluster.
A few weeks ago I bought an used intel nuc7 with a 7th gen core i5… for 150€.
It came with a 120gb ssd, 4gb ram and a power brick.
I still don’t see the value in this SBCs used as home servers.
