I have a concern with your design since there is no de-humidification, is there a risk that fog, rain or high moisture will end up in your miners and cause damage? It looks to me you have a simple exhaust fan set up creating negative pressure in the container and air is supplied through the bottom filters. This does not address potential moisture concerns?
Thanks for the help. Did you find a partner in NA to sell these units after? I live in Canada
Thanks for the info Polivka, intriguing stuff

CryptoKube has a cool set up, although too expensive. Doesn't appear to be selling them anymore

I am wondering if you ship to the United States and how much would it cost to send from Austria.
Cause the person who asked you about this is right. That company doesn't sell them anymore that is close enough.
