I've seen a few Xmod heatsinks lurking around that are lapped and polished. So i am soon planning to do this. I've done it with a few CPU heatsinks already so im hoping to use the same process.Now I was planning on possibly writing up a tutorial with pics on how to do this but before i spend the time to write it all up was wondering if there already is a tutorial or if someone else is writing one...just so i dont waste my time writing something useless.
