If mini computers are still relevant, then maybe a NXT branded case could be an idea for conferences. These are mockups, but embossing aluminium could be an idea to give the 'forge' industrial look. I'm thinking of cutting/routing out the NXT logo, which would also act as a vent. This would look professional. Etching NXT Crypto could also be a idea. If anyone thinks this is worthwhile or has similar ideas, let me know and I'll keep tinkering.
