All services are split across 2 DIY servers (in towers). 15TB of media stored on HDD with btrfs duplicated across both servers.
One server host is Alpine Linux, the other is Opensuse MicroOS. LXD containers usually are Debian 12 or Alpine.
I'm beginning to migrate some things to a cluster of (12) raspberry pi 3s. Unsure what to choose for rpi's, maybe, Fedora CoreOS (ublue), although Alpine does work extremely well on them (once you get them set up with it).
+ router running fresh tomato :)
Also mailcow for email, on a VPS, although I need to switch to a new provider, having difficulty with delivery using Linode and OVHCloud.
