Once upon a time pc enclosures were intended to limit EMI/RFI. What about the common plexiglass side panel windows that are used nowadays? Do these significantly increase emissions?

Got to think so, depends on the type of emissions....
Recently at a computer store my teenage son and I walked by a display of the latest in gaudy cases with large transparent sides, numerous multicolor LEDs, fans with LEDs, ad nauseum..
I paused in front of this thing and proclaimed, "This is the case to get if you want *everybody* to know ... you don't have a girlfriend!"
The salesguys nearby laughed. One customer turned beet red...
-- Namaste--
With the advent of DIY computers the FCC pretty much gave up on the idea of cases being part of the RFI solution. PC hardware that is sold to consumers has to pass the tests without a case[*] and gets spotted 6dB. [*] No case on three sides.
Even worse:
-- You can\'t have a sense of humor, if you have no sense!
A modern motherboard would qualify even in a cardboard box case. They just do not radiate the way they did in the 5 Volt logic days.
However, I would never put my PC gear into anything other than a nice Faraday shielded cage type case.
