@plmokni The key to finding information like that (schematics etc) is what and how to search. Your motherboard is model number zaa x32 so you should Google zaa x32 schematics and zaa x32 boardview. (Both are available on the same place and even in the same post, in one of the very first results.)
We don’t post links to such here on iFixit as it’s copyrighted material, but the information is out there (at least in this case).
You said the MOSFET got “stupid hot” and there were shorts on the caps, how did you measure the shorts and what is “stupid hot”? MOSFETs tend to get quite hot, that’s why they’re often connected to a heat sink with a thermal compound (paste).
Just randomly assuming something and removing parts, without knowing the actuality is often more damaging than the problem itself. You could be making the problem much, much bigger and worse instead of fixing it.
