I think the pi isn't a great value proposition anymore especially given the availability issues. I run HA off of proxmox installed on a nuc11 NUC11ATKC4 with a Celeron N5105, which set me back about $150 USD. It runs solid as a rock, with 2 cores and 8gb of ram, and enough left over to carve out an instance for running a local game server like Minecraft or Satisfactory when I like. You could do something like a pihole or a plex server instead, easy. Don't let people tell you it's hard to set up this way...there are well maintained scripts for installing and configuring proxmox and then HAOS afterwards. Took me like 15 minutes total of basically braindead pressing enter for 'next'. The instance runtime has been completely uninterrupted except for updates for over 6 months now. I let a pi run my 3d printer but I think I'm done running any constant availability services off of one.
