chuck what? your desktop pc already is inside of metal enclosure designed to minimize EM emissions, per UL/CE requirements for electronic devices.

also Voltage is difference between two levels, "potential". so that means 5Volt dc device will work if "GND"/minus pole is 3000volts "above real earth" and positive pole is 3005Volt "above real earth"

difference between + and - is voltage, so 3000 V - 3005 V is 5 V.

youtubers can film experiment showing this.

Many desktop PCs have enclosures with one or more sides made of glass or acrylic. That does not seem "designed to minimize EM emissions" to me.
