Wow. I missed this thread when you posted it. Nice build! I wish I had a lathe to be able to make my own heat sinks. I see so many cool hosts but no may get get a heatsink for them and paying people to make them gets pricey after awhile.
Yeah I got to admit, having access to a lathe is very handy in this hobby. If you need a heatsink just ask, I will do them for a reasonable price or check with Moh. He has good prices.
