How to make a minimal install with only graphical DE?

Hello,

I'm currently using ubuntu but I really would like to try Fedora (I already tried it with the liveCD LXDE spin but there are too many application I will never use).

What I like with ubuntu is that I downloaded the "mini.iso" (<50Mb), then installed without checking anything (no "Desktop Environment", no applications, ...), then reboot and "apt-get update", "apt-get install lxde", "apt-get install synaptic", reboot and it works perfectly. I only added the applications I needed (VLC, libreoffice, chromium, htop) and my old computer work perfectly with 512Mb RAM (I only use 70 to max 200 Mb RAM!!!).

I tried the same with the fedora netinstall CD, yum install lxde, yum install xserver-xorg (it is a dependency of lxde in ubuntu), yum install xinit, .... but nothing worked to be in a graphical environment after reboot.

So my question is: is it a way to have a very minimal fedora 17 with only LXDE or Razor-Qt but no application at all except a graphical packages manager?

Thanks in advance for your help.

Thomas.
