Not to scold you or anything, but being a newbie doesnt mean you can use it as an excuse not to do ur own research.
Since there is a recommended list of parts for you, i suggest you youtube for linustechtips and input each part. He should have reviewed most of the parts. If dun have, then find other good reviewers (typically those with high view counts). From there, learn what is it all about and you will get to know better.
Simply saying not everyone knows so much sort of look like an excuse to me. Everyone started knowing nothing, but with time n researching, you will learn something for sure.
My 2 cents.
