Yeah, I'd agree with that. Everything has a specific place it plugs in. So I suspect even people who get overwhelmed would eventually figure it out. Probably the only question would be putting memory into the optimized slot/banks, and of course, not destroying the CPU socket pins when you drop the CPU in there.

I build my PCs specifically because I save money. It's not that I dislike building them, but if I could pick it up all put together with the parts I want, and with a base minimal Windows 10 OS installed at the same price, I'd do that. Could be I'm lazy, I dunno, just other things I would prefer doing if given the choice.
