Thanks for all the kind words, everybody! This has turned out to be a really fun project—due in no small part to how supportive, easy to work with, and understanding the folks on GeekHack and Deskthority have been.
I'm currently waiting on the "enigma black" powder coated cases to come back from the finisher here locally. I'll get those shipped out and will then turn my attention to new projects, since this one has gone so smoothly, which I have found very encouraging. Again, I want to express my extreme gratitude to everyone for making this such a surprisingly painless process. :)
