Day 64: Computer Processor/Heat Sink

This big hunk of metal has been sitting next to my desk ever since my brother replaced some of my Mac's innards. I thought it was just there until I got around to finding out how to recycle it but it turns out it is still useful -- and not even as a paperweight but as an actual computer component. It is a mark of what a deep technonerd my brother is that he just assumed all humans would know this just by looking at said hunk of metal, and so I gave it to him to use. Presumably as something other than a rather unwieldy but interesting-looking paperweight.
