Prices are here: https://oxide.computer/sales ;)
I am not in sales and so I hesitate to speak on it in case I am incorrect, but the way that I personally think about it is that it is true that it is not an inexpensive product: there's a LOT of computer here. But the goal is to be competitively priced.
I wish there was a 4U version (10-25K but I don't think that they could come close to that price point - regardless even that is out of reach for me to ever get to play on one :-/ )
