An anonymous reader asks: "I was talking with a co-worker today about how Google is so big, and how they make such great use of commodity hardware to do their business, and one of the topics that came up is what Google does with its old hardware. Google has been around for many years now, they have more machines than any sane person would own, and they are continually expanding. At some stage they have to push out old equipment, either when it starts entering into its MTBF limits or it's been depreciated down. Searching (using Google of course) wasn't particularly fruitful. Has anyone seen where Google's hardware goes when it dies?"
