It’ll boot right into a fully functional Gnome desktop and hardly anything else. The only extra software this installs are yelp, gnome-shell-extension-prefs and network-manager-gnome. Uninstall them with sudo apt purge and sudo apt autoremove --purge if you don’t need them. sudo apt install cups if you need printing and remove your wifi device from /etc/network/devices to let network-manager-gnome handle wifi if you use it.
