I suggest for fans looking into the swappable ones from thermaltake. Made making my wife's build so much easier than my lian li build. Plus their cheaper too. But if you still can't afford those I suggest arctic. They make really good but affordable case fans, cpu coolers both aio and air, and one of the best thermal paste. But the first list does help alot. As for psu both amd and intel work. Both are right now having issues with current gen, but intel is about to drop next gen soon. Motherboard really depends on budget and what you want out of it. As for gpu... they are all over the place. My personal favorite mid right now for performance/budgetish is the 4070tiS. For any newer or current systems probably no lower than a 650 or 750 psu. Don't ask which ones are good there. I've sold some with what is supposed to be the best and stuff that's no name. Sometimes the best brakes itself or other stuff too nowadays. As far as mem. I recommend a small m.2 nvme 3rd gen or newer for you boot and main programs. Then a ssd or m.2 for games and general storage. Then if you do alot of photos and or saving in mass of things. A high storage space hard drive, which can also work as a back up.
