Mac OS 8 server

Hi- I have an old Mac in the corner of the office, and I want to set it up as the "jukebox"

I've loaded up some MP3s, and am currently using Winamp ( iTunes download failed twice) but what I want is to create a voting system so that once a song has been heard too often, people can vote it off the playlist.

I can do this easily in a Windoze environment with ASP and Flash ( or at least I think I can! ) but as its a Mac that is not- and cannot- connected to our office network, I'd like to make it a small server, then I can have a live website for voting.

Any suggestions for a free Mac server that supports either ASP or PHP? Or, in fact, any CGI, what I will be doing is very simple.

Thanks
