I have mini-ITX board in a mini case. 4 bays, 16 GB RAM of DDR3-L and a slow but very low TDP CPU. This thing is very low power but it’s on 24/7.

Runs home assistant with zigbee, rtl433 and whatever it detects over the network. A few older game servers (minecraft, minetest/luanti, quake 2), miniDLNA, … Arch Linux, so rolling release and always up to date with the latest versions.

Served me greatly and I haven’t upgraded because it still does what I want and I can’t find any modern CPU with a TDP this low.

That would be the KVM OS.

That’s simply a matter of numbers. More people = more content, but people can’t seem to get past the fewer content so they don’t join/stay.

A catch-all email server. I have a limitless amount of mail addresses going to me and my wife’s mailboxes. When an address gets leaked or start receiving spam I immediately know what company is to blame.
