Replacement PCB for maxtor drive?

I recently fried my HD(note to self: don't touch power cables while computer is running).

Now it's all klicky klicky and isn't detected by anything. Anyhow it probably is the PCB that lost it's life, meaning that if i get the right pcb i can ressurect it. It's a Maxtor drive and the internets tell me i more or less just need to find a maxtor HD with the same PCBA code and swap the boards while ignoring all the other numbers and whatnot. Is this really the case or do i have to mind any other variables now before i start chasing retired maxtor drives?

The internet tubes tell me it can klick because of faulty pcb. And as nothing manage to detect the drive i'm pretty sure that the pcb is fried. My other drives that have gone klicky have atleast been detectable and readable to some extent while this one is dead as a rock.
