Hello all of you. I am completely new to this, I got my hands on an old pc (Fujitsu Celsius M470) that I would like to use as a NAS because I really need the Moments app by Synology, for creating shared photo albums with face recognition. I also have 4 spare HDD's that are ready to be used. So, I want to do a clean install, but I have no clue where to start. I found some old tutorials (between 2012 and 2015), but most times the links don't work anymore. Can anyone point me to a tutorial for a clean install with working links?
