Gaming Server

Since Prime keeps forgetting to give me access to the LAN planning forum

I will start this here.

I now have a quad core CPU we can put to good use. I thought I would build a system with 8GB of ram, the Quad, 64-bit OS.. blah blah and we can use it for the game server (should be able to run 3 maybe 5 games on it?..maybe all?)

What OS? Linux or Windows?

Throw in your ideas.

Thanks
