Someone at another forum claims that his computer had been "blown up" once because of all the traffic it was getting. Specifically, "the chips were getting fried by excessive line current from the network. i had the only broadband server on a twisted pair copper network and i was almost a mile from the POP into the fibre net. all the big services were trying to push my neighbor's internet through it and chips would melt down on the motherboard."
Is this even possible? It sounds unlikely, but I'm not an expert.
