I'm sharing a house this school year with 7 guys and we're all geeks
I've been thinking about putting a linux box in the kitchen area and have some server programs on it.

Notable specs are: 3.0ghz P4, 1gb ram, 120gb hdd + 750gb external.

I'm going to be putting a DC++ server on it so we can all swap movies and files across the network.
I'm also adding a ventrilo server for in-game chat
and
LAMP for a joomla blog or two.

What else could I put on this that would be awesome?
I also have a dd-wrt router.

Thanks
