On the same note, can I suggest that you get some panel mounted IO ports. Like this panel mounted USB port - http://www.adafruit.com/blog/2012/08/23/new-panel-mount-usb-cable-b-female-to-mini-b-male-and-panel-mount-usb-cable-b-female-to-micro-b-male/. One for the ethernet cable and solar panel connectors would look great too.
...
Also, purely from an Electrical Engineers pedantic perspective - I would mount a small fan running at low RPM on one of the sides of the box to prevent the entire thing from overheating.
...
Even removing the casing from the batteries might make the whole thing look a little bit cooler (by doing this you can access their power switches then, such that you could daisy chain the power switches to one master switch mounted on the front of the box).

Well, I wont turn this into a Barebone/Desktop computer. This is just a "chep" solar powered RasPI, nothing more. If I would add all these things, it would become expensive and time consuming. Open the battery case can be done at the conference to show off. A fan would take ~ 1 Watt more, that would kill the complete idea. Temps in the sun are ~ 63°C, so nothing to scare about.
A couple of NXT stickers on the sides of the box, line the insides with strips of LEDs, a bit of cable management and it will look amazing. It's the little things that make a setup/prototype like this. From experience, if you're going to do this you have to do it right and not have it look hacked together. That will scream the wrong message at people - "You can only do something like this if you are a genius".

It is still a prototype, but what about this photo? I leave the stickers done by the conference people

Keep up the good work!
