Well, thanks for all the great ideas. I think the Millenium Falcon would be a bit unweildy, and I lack the plastic-forming skills to make a replacement wedgie case. HOWEVER, I have just won an eBay auction for a CD player, and so i'm going to make an A1200 based CDTV style computer.
To start with it'll have to have an Amiga 4000 keyboard and beige monitor, but in time i hope to source a CDTV keyboard, and i'll probably spray my 1084S black, or something :-D
I will of course put pics online as i work on it.
