On Fedora 7/8
yum groupinstall "GNOME Desktop Environment"
And you will have quite a lot to download and install. What I did is use the repository on the DVD, so i didnt download anything, and the installation went really fast.
To do that:
/etc/yum.repo.d
vi Fedora-install-media.repo
in [InstallMedia]
name=Fedora 8i
baseurl=file:///media/cdr
...
That should to the work!!
cdr above is the folder i used to mount my DVD
mkdir cdr
mount /dev/cdrom /media/cdr
Good luck
