I just got my used T17 42T today and when unpacking i heard a rattling noise inside 3 miner. so i decided to have a look at one inside before i plug them in.

At one hasboard 2 capacitors became loose. as i have soldered such a thing ages ago i wont do it by myself (also dont have a good workspace for that).

is there anything to take extremely care or is it just resoldering? for what are these capacitors needed i just found voltagemonitoring? (would they work without x)? can i just take one hashboard put it into another same model so i can make 1 good miner from 2 or are the boards "bound" to their miner or place in the miner?
