This, a perfectly adequate solution.  Or LXDE or mate or LXQt or fvwm
or just X with a simple xterm that he uses to start his custom app.  I
think cinnamon or KDE would be roughly the same size as Gnome, so
probably not viable alternatives to reduce memory usage.

He could also compile a custom kernel tuned to his hardware from the
x86_64 src.rpm, so it is smaller.  The spec file could even be set up to
build a 686 kernel from the source, if that is what he wants.  He would
have to fix any problems himself, though, to do that.  He could share
his results in copr for anyone wanting such a kernel.
