LOL. "I am disinterested in doing [a thing] that I don't have to do."

"Hurr hurr, ur pathetic."

Good fucking christ, this person isn't into building computers. The opinion expressed is utterly harmless and their personal preference. You are free to build all the computers you want.

Its literally easier than most lego sets these days.

Oh, yeah, anything can be super easy for people are interested in and experienced with doing that thing.

Building a computer properly is way more than "plugging parts into marked slots," and your comment is disingenuous at best. RAM timings, socket types, cooling selection, power supply selection, wire routing and dressing, version/generation conflicts, Red vs Blue, will the GPU even fit in this computer case, counterfeit parts... And this is all before the thing is plugged in.
