Protects your stuff from EM radiation and stuff, but is this really a concern in e.g. a PlayStation 2? Are they a relic from the past? Is there any proof of them harming electronics?
In: Technology
In most cases the RF shielding is actually not to protect that device but to keep that device from interfering with other devices. It is required to be limited so that it doesn’t interfere with other devices under federal law.
Pretty much any modern electronic device transmits information over wires internally at one frequency or another.
How do you create a radio transmit a signal over a wire. So basically all of these devices give off some EM/RF.

“This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.”
That is probably one of the worst worded statements. By accepting interference all it means is it won’t try to interfere with the outside transmission. You could operate your device in a Faraday cage and ground it. The chassis could do that. That would be legal. It would accept outside interference that way without interfering back. It is just grounding that interference.
