My server is nothing but a file server which is why I'm opting for software like FreeNAS. If I wanted to stick with an actual GUI OS I would continue using Windows 7 as there isn't any learning curve involved with using something I'm already proficient in. Simple webgui interface that I can control from anything like my tab or phone and file sharing properties is what I'm after. Not to mention, I can do port bonding with it and such.
