Currently running Ubuntu 10.10 server with Virtualbox headless. Works alright, but the overhead of virtulization isn't working for me. ESXi will not work with my box and VMware Server doesn't seem appealing. I'm now looking into just running a Windows server OS on the machine. Not sure what to choose though. Use the box for media sharing, file sharing, game server, WAMP stack, etc. Would 2008 Server R2 be sufficient? If so, where do I snag a copy. Obviously I am not paying for a copy as this is just for a home server. Any help is greatly appreciated.
