If you really want kde only to be installed in your system
what i have done is during installation when asked for workstation or server unclick all mean not install anything but bottom there chose
customize
the problem is you really need to know the software need to use for kde only but if you understand the software you need ( run with kde ) should be good then your installation might fix to less than 2 gb
if you accidentally chose software which is required gnome then gnome will be installed , so avoid that
its work for me this way , so my system only use kde for now is kde3.5
i have use fedora 9 but revert back to fedora 8 because there something i not satisfied with kde4, i want to wait fedora 10
5 cent from me , cheers
