I got a server now what?

hey guy is was looking for something new to learn so i got a old server. Its a Dell PowerEdge 860 just a cheap second hand server. I wanted to know what should i do ? anything good to try on them ?
I wanted to maybe setup some game servers to play on with friends or web hosting.
I would really like help getting started with servers so anything will help.

Have you checked out the TurnKey Linux servers? Very easy to install.

or if it's an older 32bit machine, you'll find them on SourceForge.
