NsCDE is amazing it genuinely has like the most consistent look of any desktop I've used and it looks so good and works so well
TDE's CDE window decoration style pretty much matches the screenshot. There's also a matching widget style (Motif). I'd guess that the icon set exists Somewhere Out There On The Internet. So you can get this look if you want it badly enough to install a non-default DE that's currently limited to X11.
I've looked into CDE before but the support seems pretty poor compared to Chicago95
Sinclair-Speccy@fedia.io to 
Legendary icons for Home and Root.
I'd kill for a functional DE that looks like this. Currently using Chicago95
