Hi N1c0_ds
Go with Debian for this. If I were in your shoes I'd go through the list of software you use now and write it down. A la Gimp, Pidgin, OpenOffice, etc. Install Debian with just the base system, do not install the desktop software. When you boot up you will be greeted with just a plain cli login.
Login with your set root password and do the following:
apt-get update
apt-get install xserver-xorg gdm gnome-core synaptic
reboot
It will now come up with a basic Gnome login and then you can pull any any extra packages you require but the basics will be there ready and running
BTW, Gnome-Core pulls in:
gnome-control-center
eog
gedit
gnome-applets
gnome-icon-theme
gnome-menus
gnome-panel
gnome-session
gnome-settings-daemon
gnome-terminal
metacity
compiz-gnome
nautilus
rarian-compat
scrollkeeper
