This looks really good.
What I would really love is if you could make a transparent case. Black is always really hard because of the keys and a computer with black case and white keys looks awful. White on transparent is alright though.
Also at some point if this is as success, maybe you can consider small form factor A600 cases with the same mentality.
59 is still not that far off from the 79 the other case project asked for, so I still think it's a bit steep for my liking. But am really glad you guys are working on this and I wish you the best with the crowdfunding campaign.
