Personally, I bought one of their units, just to see how it plays out. After chastising them for emailing me my account password in plaintext, of course ... (they fixed that immediately after I brought it up, so props there).
Real engineers or even good managers must know already that design doesn't matter in bitcoin mining so asking someone to make some pretty renders of possible boxes tells me that you are focusing on the wrong stuff. Designers know shit about cooling and airflow and other stuff. They should be sourcing parts and workforce and other stuff not make useless renders and also saying that you can't have a still photo of a case that is supposed to be already present long before chips arrive makes me wonder how can they manage a proper assembly chain. Their chips might be legitimate, but everything else is way wrong.
