I think this topic, to share, information about hardware for mining.
I have thought build a machine with 4 graphics cards “Sapphire Radeon Nitro Plus RX 470 8GB GDDR5”, expandable to 6 in the future, I would like to have a thread to share information about the hardware used by other miners. At the moment I have the graphics cards and I would like you to recommend me a motherboard.

Most motherboards have 4 or more PCI-E slots (mix of x16 or x1 slots) all you need to have is PCI-E x1 powered risers and you should be fine on 99% of boards.
You’re right, but I intend to do something powerful, and economical, there motherboards that work better or are more compatible with other components, and the ability to expand or improve in the future, others not.
Only downside to going cheap on the CPU would be that once a dual-mining software that can use CPU+GPU comes out, a more powerful processor could pay for itself in mining.
Considering that a middle of the road i5 processor currently hashes at around 1/4th of the speed of a high end GPU i have a hard time seeing it not pay for itself to spend the extra $50 or so to mine with CPU as well.
You are correct however. What might arise is an issue where the CPU is ‘bogged down’ with controlling the GPU’s and won’t be able to mine at a reasonable rate, or even interfere with GPU mining capacity if it does so.
For now, I would probably go with an i3 or cheap AMD as well if you want to be on the ‘safe side’.
