This looks very awesome. How much did you pay for all the parts in total and what would be the price if you would do a 4 chip version?
I think this kind of DIY could be an awesome hobby and could repurpose a large amount of useless miners for heating equipment and other nice inventions.

NOTE: Persistent Inventory shortages are making production price per board spike because the parts with small or no inventory will tend spike between 40% to 300%

I think if you add the total production cost of PCB fab + PCB Assembly Time (by yourself or at the factory ) + PCB Parts + shipping . Starting with a batch of 5 pieces

NOTE: i am assuming no BOM part shortages in my prices.

1-Chip == $70 / Per PCB Board
2-Chip == $90 / Per PCB Board
4-Chip == $125 / Per PCB Board

Obviously this costs can come down considerably once your streamline the parts on BOM, replacing parts which have inventory shortages with similar quality alternatives parts and order a bigger batch of say 100 or 200 or 500 per run. I think we can lower the production cost to about

1-Chip == $50 / Per PCB Board
2-Chip == $70 / Per PCB Board
4-Chip == $90 / Per PCB Board

when streamlined.

Not sure what other users are paying for their initial total prototype PCB cost. Because of shortages of some major parts the prices will differ considerably. There are only about 10 parts that are good to have but all the parts can be replaced with similar alternatives if you can figure it out.
