And bear in mind KDE3 was considered the bloated DE, as XFCE (even the GTK2 build) could snappily run with 64 MB of RAM and maybe less with a light GTK engine (yes, choosing the GTK2 engine mattered a lot back in the day).

And, yes, choosing Pidgin and a light window manager such as Fluxbox/Openbox could make run machine run well with 64MB at really fast speeds.
