my question is fairly similar to this, but I'd like to be more specific. Quite a few years have passed since it was asked so it might be relevant to ask again..
I got hold of a pretty old piece of computer (core2duo CPU, 2 GB of RAM) and I though that now, finally, I can run a little home server with a few services: Postfix for email, Apache for a webserver, and Samba for local file sharing.
It has been years since I've used any form of Unix, so I'm curious, are there any actual advantages (performance, flexibility) to running those on Free/OpenBSD? What are the advantages of running the same applications on CentOS or Debian, except that it's just way more common? I would also guess that there are more drivers available for Linux distributions.
