the hardest part is amiga layouted keyboard. you will have hard time to beat cusa here, for the case himself you can use some sort of automated fabrication, say 3d printer. shouldnt be much of an issue.

@daddy
sorry but without amiga keyboard layout and some more design characteristics, and especially if done of bent metal it resembles more just any 8-bit computer replica like many built in eastern block.
check for instance this out:
http://pl.wikipedia.org/wiki/Meritum_Ihttp://pl.wikipedia.org/wiki/Meritum_IIhttp://pl.wikipedia.org/wiki/Meritum_IIIbesides wedge computers were not only amigas, there were many other such case designs in the early 80s, many better, like -say- atari_st. why do you advertise your design an amiga replica? it should rather be treated as a wedge computer replica in general and meet the wider audience. although from this angle i still find the following cybernet design, (marketed currently by cusa afair) by lengths more elegant and likely more functional than anything you can build at home.
