Agreed, i could give him one of the A500s i have up in the attic but that would propel him instantly into floppy failure hell, just like it did for me, all those years ago.

According to that wikipedia article, the minimig is "nano-itx size". However, it seems that via's nano-itx only has ports at one end of the board. Because of that it looks like you wouldn't easily be able to fit the minimig board in any of the existing nano-itx cases on the market.
Any ideas?
