Which CPU family and which series? Once you finish THAT, everything gets a lot more straightforward.
That list is terrible. At least order the families/series chronologically.
If I'm a reasonably informed random, I know to click a handful of things with "lake" in the name and a handful of things with "zen" in the name and that's about it. Except you can't do that with the chooser as it gives you zero choices, since -zen is a series and -lake is a family and those are disjoint (I should be able to union those).
As a noob, I would miss any of the "gaming value" choices with that heuristic (Haswell/Broadwell that are quite nice).
I don't see any EPYC in that list, so I'm scratching my head (yes, I know it's a server but a random person won't) and I would miss the Threadripper choice (why doesn't it have Ryzen next to it).
The problem isn't assembling a PC. It's the fact that PC knowledge has a half-life of like 6 months, and you really can't trust review sites or web searches on this topic anymore.
Maybe that particular filter on that particular part isn't that easy to use but I think sites like this make building a PC extremely approachable, even for someone who has never built a PC before.
The problem, as a noob, is that you don't even have enough knowledge to use the filters correctly.
Should also be mentioned that the manuals that come with things like motherboards and cases are much more detailed than they used to be.
PCPP is really revolutionary. Building a PC in 2018 should be easy.
The only priblem is a lot of everchanging technologies and acronyms, e.g. NVMe, M.2, etc.
For others, even just pcpartpicker can present an overload of information.
I don't keep up with current events in custom PCs and when I built a PC last year [2] I thought it was incredibly straight forward.
