And most importantly: as of recently I'm self-hosting Lemmy and Kbin instances for myself to try them out! Kbin was a pain to setup, but I seem to be liking it more.

It's all running on two Ryzen R7 1700 systems with 64GB of RAM in one and 48GB in the other (long story), and virtual disk storage is done over a 10Gb iSCSI link to a TrueNAS system with two 1TB SSDs in a RAIDz mirror. I've also got an unRAID NAS that hosts my video project files. Pretty smooth overall :D
