Hmm... Pretty cool. I really dig the copper fascia. The DVD, floppy drives, fan controls and Amiga logo bay cover should have been done up with that, too.
I've never been much for transparent case mods, though... Especially when they reveal a rats-nest of wires and sideways jammed in expansions. It might be a neat effect if you tinted them dark and added a bit of a backlight, though.
Come to think of it, I might do that on my own project. :-)
