Finally I gave that up, in time. GPU is also to slow these days. So I tried to find some quiet R4 miners. But all I found was scammers and sould out web pages. Then I tried to buy some noisy stuff from bitmain, but all was sold out. I have concluded that the best thing is to mine etherum with GPU, and exchange them to other cryptocurrencies. And I also found out, that it is the most silent, fun and interesting solution. Most of the people that are into this, are here because of quick money. But the more I work with it, the more interesting the whole technology behind it gets. So no I will try to built my first rig. And I am glad that there is a forum where it is possible to communicate with people that also like technology, and not only selling expensive things on ebay. So here are my suggestion so far. Please tell me what you think. And I also wonder why some graphics card seems to have same name (Like Radeon RX), but not produced by the same company...? What is the best graphicscard to mine, in my list? Thanks!Motherboard: ASRock H110 Pro BTC+ Socket 1151
