I'm going to take an idea from the Vita and throw out some latin words
Affrus- horse for farm work (would make it afrus) (only 43,000 hits)
Imbrium - Of rain
I sort of like the sound of Dragonbox: Afrus
Of course the entire problem, in my opinion, with naming by model is that it's difficult to keep track for people who don't have one. For that reason, the model name doesn't really matter. If I have one of these, I will refer to it as the Dragonbox to other people, simply because that refers to the brand and will most directly take them back to the site, whereas if I have two different models and I refer to them by their model name, it's not clear that it's from the same manufacturer. In fact, we could simply call this one the Dragonbox, and then later models, just refer to them by Dragonbox One, or something similar.
