The closest I know of is Blue95. I have only run the live environment but it worked pretty well and was impressive.

"Blue95 is a modern and lightweight desktop experience that is reminiscent of a bygone era of computing. Based on Fedora Atomic Xfce with the Chicago95 theme."

Depending on your chosen desktop and era, there are also things like TDE (trinity desktop environment) a fork (or spiritual successor) of the KDE 3.x environment: https://www.trinitydesktop.org/media/screenshots/large/tde3....

And if you like Gnome 2.x, there's MATE: https://mate-desktop.org/
