Anyone know how to install a really lean desktop like LXDE or XFCE ?

I am really not a big fan of the big massive GNOME desktop or KDE which has every bell and whistle anyone could want. I am happy, very happy with a very lean and simple interface like LXDE. Even ye old TWM would work but that is perhaps a tad too lean and entirely too mean. I went looking for lxde and see not much :

# yum search lxde
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
======================================================== N/S matched: lxde =========================================================
lxmenu-data.noarch : Data files for the LXDE menu

  Name and summary matches only, use "search all" for everything.
# 

So not sure what to make of that.

I think building from source may be a bit of a long haul : https://wiki.lxde.org/en/Installation

Any thoughts ?

I found the sad news here :

Does Red Hat support the XFCE Desktop Environment on Red Hat Enterprise Linux?

so Computer says "no". :-(

I have to look at a total build of my own into $HOME somehow.
