For me personally… I use VyOS in a VM running on a proxmox host (optiplex, SFF) with a 4-port NIC passthrough. This solves the issue of power for me, as the host has plenty of ram allowing me to run other services without needing an additional machine (although I do have one as a spare). VyOS doesn’t currently have a GUI (one is in development), however, it has been very solid for me (also based on debian, which is nice).

Then apply changes. You should no longer have that annoying banner at the bottom of the page
