Not to disagree at all, though familiar with ferrite cores had not even heard of ferrite beads before modifying the 5 chip miners, but will just point out that some of the later blades did ship with 0 ohm resistors in place of the ~~anal~~ ferrite beads.

Everything is fine until it's not. The factory need only keep it working for as long as the warranty period lasts.

I assume that ferrites are there because of high current and when connect it it gets a big current shock which is dumped by those ferrites, 0 ohm resistors can replace that.
But I think there are not 0 ohms but in real some 0,5 or 0,3 ohm

That is one of their functions, yes. Switching pools, temporary disconnections, even coin switches might cause current surges. Eventually, that is going to kill some parts. With the incredibly rapid pace of profitability, I imagine these will need to be running a long time to make back their cost. That is a consideration for me, anyway.
