you can buy "new" vintage spec computers. There are still companies that sell them.
Many restaurant P.O.S. (point of sales systems) you see at places at Jack-n-Box and the likes source Windows 95/NT 4.0 computers new from resellers.
I don't know where they source monitors (SVGA (800x600)) but they do.
And of course, Windows 95 would never be on the network.
