Thanks everybody. It was a complete surprise and very nice to receive.

I got it installed in my Mac Pro without too much trouble and moved my OS and home folder over to it. Things are fast! A clean build of Airfoil takes about two minutes now. (I don't remember exactly but I think it was more like five minutes before.) More importantly, so many things that used to take time, like starting apps or incremental builds, now don't. Hooray!

I left the plate on it for now. I can't see it that way, but I like keeping them together. It causes no trouble inside the Mac Pro. If I ever put it in a laptop and the plate interferes, or if I just want to show off the engraving, it is really easy to remove.
