This should install gnome:

dnf install @gnome-desktop-environment

A few other things that I found helpful:

1) I got lots of disconnects with 1 Gbps Ethernet, so I added the following to root's crontab (via crontab -e) to force the ethernet down to 100 Mbps:

@reboot sleep 10 ; /sbin/ethtool -s eth0 speed 100 duplex full

2) I was not able to login on the console serial port, because plymouth was interfering with agetty.  I removed plymouth via:

dnf remove plymouth

3) I had a problem with overscan - basically I had a black border all around the screen.  I fixed that by editing /boot/efi/config.txt and adding this line at the end of the file:

disable_overscan=1
