I’m really enjoying this project, and I like that green! I agree with the white looking clinical, have you tried the green with a softened black, like a charcoal shade? The renders look great!
Is there a way to make the cable solution suit the intended portability? Maybe a quick connector or mini dock style thing that fits nicely underneath? The way I’m seeing it the cables connect at 90° to the bottom of the case, which could make it hard to fit hands underneath to plug them in and pull them out with that orientation.
