A year or so ago I was gutting computers for handy pieces of metal (primarily the sheets for the case sides as well as aluminum heatsinks). One of them happened to contained an old Intel 486-33mhz CPU, circa 1989. As far as I’m concerned, this was the chip that really brought low cost home computers to market. I removed it from the machine and am planning on making it into a paperweight using an EasyCast clear epoxy casting kit. My dad did a similar project when he was younger except he put coins and stuff into his.
