I originally got it just to install OPNSense firewall on it, but realised that with Proxmox installed, it can quite easily run 2-3 small VMs, including a node box. Quiet and efficient.
Oooh cool, never heard of that one before!
I hadn't either until I saw it on @k3tan's website!
Do you have a link?
I think it was in this post where I first saw it mentioned and started looking into it.
