I have two actually. One umbrel and one core running on Linux desktop
Discussion
I wasn't happy with my Umbrel. I was running it on top of my Linux laptop. Bogged it down. Umbrel felt insecure to me.
Currently syncing Bitcoin core on my laptop. No frills.
I am actually pleasantly surprised by umbrel. My setup is over kill and have it running on a old HP desktop. It’s been a fun project and runs well.
Maybe run it as a VM on proxmox if you want to isolate it from the rest of your setup
