Before cloud was a thing, I used to run an OpenBSD web server in my bedroom on my old desktop. I set it up after my commercial web host was hacked for running outdated Apache.

I stopped using OpenBSD when I tried installing it on my newer Core 2 Duo desktop in ~2008, but the OS would not boot, and I was told on IRC by OpenBSD developers that the hardware was too new for OpenBSD.

FWIW, now I use Arch Linux. I guess I'm in the target demographic.
