Going back to specifics if your going to run a mining farm you're going to have to learn as you go, debug the hardware equipment and software, find ways to better optimize cost of equipment as you build and go on. Even if it's not the most optimized your fighting against time so you can make a few mistakes and keep improving as you go. Ditch the shopping list and just do it and build your 1st fully functional working rig. Once that's running perfectly you'll build your next rig cheaper and more efficient. Start small and expand
One of the best comments I have seen on these boards for quite some time. Very well said.
lol my rigs get more expensive with newer builds since i realise i need more power over head, better more powerful GPUs ,Better motherboards etc not cheaper
