There are companies who can make a silicon cast from a original case and that can be used.. but would need a supply of cases as they get broken when the cast is removed.. and only good for about 10-20 copies.. still talking a lot of money and would still end up being like £300+ a case easily
It has been suggested before.. But the Atari MB is to long for most PC cases.. if someone re-designed the ST into ATX form factor then that is a better idea. Would only need to 3D print the back plates.
So if I do design my "Super ST" likely it will get remade into ATX form factor.. then not so much a problem for upgrades/space etc and cases are not a problem. Though its not a "ST" style case anymore..
The MEGA ST cases are smaller, so cheaper for 3D printing, that could be more realistic to do.. but really, why bother, just design a new ATX board and use a off-the-shelf PC desktop case instead..
Someone else in the world near india for example could get stuff done cheaper as its local to them.. but for UK.. prices are way to expensive.. Even going to China for stuff while cheaper is still expensive.. but then shipping 1,000 cases overseas.. expensive again.. then I would have to ship them to people.. its to much shipping costs where it be cheaper to get them made in the UK
Maybe if someone knows the guy doing the Amiga kickstarter.. then can ask what company they are using to do the molds ? I might have spoke to the guy before.. can't remember..
