These were 1000uF 6.3v caps. I was hoping the board was salvageable, I'd just fired it up to check that I had a working baseline when it went pop...

Is this short likely to have caused other parts to fail?

Is removing the dead MOSFET and trying to power up the board a safe thing to do?

Fitting the new SMD mosfet to the PCB is gonna take some skill and care

though.

Yeah, I've only got a 40W iron, the caps came out reasonably easily using a heat gun to pre-warm the board. I was hoping to do the same with the MOSFET.
