Just a suggestion... I think if I had a spare A1200 mobo, I would mount it a few inches off a piece of plexiglass with some standoffs. Pop in an accelerator, a pico PSU, a couple of small speakers, USB, Fast ATA, sound card, scan doubler, slim CD-DVD, some heat sinks with multi-colored led fans, USB keyboard... you know, the works! Then use some 6" or so stand-offs to mount a piece of plexiglass as a top cover and not even mess around with a case. Maybe fashion it so you might even fit in a mediator board. That would be cool! :p
