Gnome/KDE Uninstall

I have a Linux 7.3 server running at a local NOC as a web server and I do
all my own system administration remotely via SSH. I'd like to remove KDE &
Gnome since they are unused and tend to clutter up the system. I tried a
query via rpm to see what is installed, and both appear to involve a
bewildering collection of individual packages. Does anyone know of a single
uninstall point for each of these apps? What a mess!
