Well that's it, I've bought a fanless x86 mini PC, I'll install Proxmox on it and run my stuff that way. The Rpi4 is powerful enough for almost everything I need but it's very brittle and sensitive. I've never had luck with using a SSD with it for some reason (probably overheating USB controller), and the form factor with its flimsy power cable is anything but robust. I need more stability in my life ;)
@stooovie good call! Migrated away from my armada of #raspberrypis last year (to an old zotac, which runs only #homeassistant, a dedicated #nas and a beefy optiplex for #plex et al.) and have never looked back. I guess running constantly at the limits of performance is not good for any system. #proxmox is nice but centralisation of everything on one machine, even in containers and virtual machines, has not worked well for me. I hope you have better luck!
