Windows is a no-go for sure, my daily PC is running Kubuntu, not the most hardcore Linux but way better than Windows and iOS.
I hesistate to run Proxmox as my new NAS/home server but went for TrueNAS Scale instead, not so easy but probably easier than Proxmox.
The Karaoke et dance games are running on Linux so I could go with the prebuild environnement with Docker but then what would be the advantage from my Umbrel on RasPi4? Is the power really improving the node reliability and speed? Beside the Mempool app that freeze and I need to restart every 1-2 months, it seams to be all fine, I have BTCPay Server and LNbits, Nostr Relay and couple of other apps related to Lightning.
