According to an EE friend, the FCC specifies EMF tolerances (max outputs) for PC components, including cases. However, here it says that there are standards for a number of components but not cases.

1. Am I understanding correctly that there are no requirements for cases?

2. According to the EE in question constructiong a PC case from anything but (mostly) metal will result in excessive EMF radiation for my purposes (audio) leading to stray signals. Furthermore he says that ventilation holes (number, diameter, and position) are calculated based on stray em wavelength. Is this the case?

3. If all of the above are the case, is there perhaps some lining I could apply to non-metallic enclosures to control stray EMF?

Many thanks in advance
