Hello! Thank you for your interest and sorry for the delayed answer. You say it's expensive - but what do you compare our device with? We say about our Cominos that they are engineered, not just assembled. In fact, they are rather cheap for the quality you get. All our component parts are provided by world-known companies:
-riser cards provided by Molex
-power supplies designed specifically for Comino by Chieftec
-radiators designed specifically by Hardware Labs Performance Systems
-fans are produced by Noctua
Comino has a special design inside which allows us to place video cards separately. As a result Comino is 5 times smaller than any other mining farm.
Comino is
-exceptionally quiet machine
-plug and play device. It is very easy to use, there are just 2 buttons.
-eco-friendly. Comino PUE is very low. It varies between 1,1 - 1,15 while the usual one is 1,6 - 2
Talking about sauna ) What we do guarantee is that there won't be sauna inside of the miner ) so that you could mine productively 24/7. When we talk about Comino, we talk 1 kW/h. So if you want to have sauna, you need to have about 8 Cominos for a sauna-size room ) (2,5 m2 x 2,5 m2)
