Thanks ever so much for that link! I have been looking for something like that, and getting nowhere.

Check out the Mission tower on the guy's main page, and tell me that couldn't be adapted to house a bashed Quad G5. Just adapt the Mission case modestly, and slot it in! All wood and cheesegrater!

But I am also thinking about the possibility of an LC475 in a case like the one pictured.... Hmmm.

These remind me of some of the hypothetical Macs in the AppleDesign book.
