I have put together many PCs myself, and honestly many parts aren't that important.
Power supply, motherboard, SSD and Ram will "just work", given you buy a recent product from a known brand. The +/- 5% of whatever will not make a difference to most people.
For mobo, think of features you must have ( built-in wireless?) And that will direct you.
Oh please don't do built-in wifi.
It's ok to have the adapter inside, but you should put the antennas outside. Include them in the design, if you wish.
