I've been starting to mess around with servers recently and after FreeNAS and Ubuntu, I landed on WHS 2011 and didn't look back. I use it as a media server and a backup server. My server is my 3 1/2 year old gaming computer with 6TBs. I posted a question earlier if anyone's interested http://forum.wegotserved.com/index.php?/topic/27952-torrent-vpn-skydrive-questions/
This seems like a cool forum where I can learn a lot more.
