I'm not sure which black one Tacoguy is referring to but if it's the one I think, then I'm sorry to say that was build from scratch, no cases to be found to make one like that. There are a few commissioned builders at SRK that could make you a case for the right price or better yet build it all and put it together for you, it does get pricey though.
Desktop enclosures are the way to go for easy DIY projects, I love them. I only made those cases 'cause during those times there was nothing I could get my hands on to make a stick, I mean a real decent stick so I had to grab the bull by the horns and go at it, but that was years ago, now there's so much access to just about anything you can think of, building something from scratch is not needed anymore. Building a stick now for someone like myself would be a very personal thing, like Hanzo forging a sword. Not to say I didn't always took care of everything with care, but there was a time I was building sticks like 3 at a time and never really ventured into designs or anything, if I was to do it now, I would play with what I've learned plus new ideas that I've gathered form more creative builders.
