Not really to do with AGAcoin directly, but if you happen to still own an Amiga500 you may want to check out the New Amiga 500 Cases Campaign. https://www.indiegogo.com/projects/new-compatible-case-for-amiga-500-plus/x/18291379#/

I got one of their 1200 cases and it is great quality - everything they said it would be.
