I say it's akin to building a Lego set because
- Both require you to follow instructions
- Computer hardware has the advantage of fitting one way 99% of the time, if it's not going in, you're inserting it in the wrong way.
The whole process to getting to the build though, is not part of the Lego comparison. Just the building part. If you understand that 1. You should read the instructions and 2. Hardware fits one way, then you don't really need YouTube or anyone else. They're good for additional references, but really, computer hardware is essentially designed to be assembled by assembly line workers who probably don't give two shits about how a transistor works.
And in regards to the whole ESD thing, I'm the "what's the big deal?" group. Mostly because I never had an issue with ESD, and if you really want to be ESD safe, you pretty much have to work in a clean room naked, or with an ESD smock, wrist band, mat, and on a flat, non-carpeted surface. Oh and having a high amount of humidity is a plus since it's a lot harder to discharge ESD in a humid environment. I've built four computers in less than ideal environments and conditions. Not one incident, but I don't handle my components like a dumbass either.
Well in any case, you might call me out that saying building a computer is easy since I built four. The first computer I built, I had no access to another computer and the only "experience" I had was watching my dad build one years before. And the computer came out just fine.
