@grsychckn has an old S400 build video on YouTube somewhere. It might give you some idea of a possible build process in conjunction with the newly christened build guide. I think there are one or two S400 build logs on the forum here and I know
@papayo has a PCPartPicker completed build over there. That, and the official photos of the S401 on the website. Happy building!
