So am not really building the pc am choosing. So there's this site that has a offer they will build your pc and ship it to you but I don't know anything about part but I have tried to read stuff on the internet but I'm stuck on the cover bit thingy, the motherboard and the DDR4 thing. The store offers you a selection off options in every category of the build plus you get a Xbox one elite controller for free. I decided to add the cooler separately because I read that it was good and cheap and the cooler the store offers seams pretty expensive. Here are links to the Swedish store (use translate so u don't get confused) and to pc partpicker.
