Oooops, installed too many of the groups during initial GUI installation for a server.

[root@host~]# yum grouplist

Office/Productivity
Administration Tools
Editors
System Tools
Text-based Internet
GNOME Desktop Environment
Authoring and Publishing
Network Servers
Hardware Support
X Window System
Graphics
Web Server
Printing Support

Time to remove some of the rubish:

[root@host~]# yum groupremove ‘Office/Productivity’ ‘GNOME Desktop Environment’ ‘Authoring and Publishing’ ‘X Window System’ ‘Graphics’ ‘Printing Support’ ‘Graphical Internet’
