If you only asked for the 'Server' install, then this would be normal I believe, a real server wouldn't normally have X-Win/GUI.
You can try
There should be a group to install the desktop SW eg
yum groupinstall "GNOME Desktop Environment"
FYI, F12 is dead, current is F15. A new Fedora comes out about once a yr or so.
If you want long term updates, consider Centos (free RHEL).
