There's a reason that high speed switching electronics have metal cases. And it's understandable that most people don't know babinet's principle as it applies to RF antenna (basically a hole in a conductor is exactly equivalent to a conductor of that same size and shape: the case window is an antenna). The FCC wouldn't care about me because I intentionally use full metal cases for all my high speed switching electronics and monitor my RF environment from 20 to 3700 MHz over various SDR devices 24/7/365.
I'll grant that a ~meter size slot antenna (case window) is not exactly big enough to be resonant at HF but compromise antennas are the standard for HF and they still work; just because HF propagates so well even at low powers. And lets not forget they such a case window slot antenna is resonant around higher frequencies like ~144 Mhz where the GPU memory is blasting and pulling large currents over long conductors.
If the FCC actually tested a modern computers in their shipped window or completely glass computer cases they likely they wouldn't allow it to be sold commercially. But they're much too busy with politics and as long as it doesn't interfere with military use or high frequency trading they don't care about HF.
Anyway, I do see that no one is disagreeing about the radio intereference caused by plasma TVs. That's good, because they're terrible offenders.
