I'm looking to build my own NAS (basically a DIY NAS) and I'm planning on doing it cheap, but not too cheap. One thing: I would invest in a RAID card setup but it's not a necessity. How should I start? Hardware / software? This is pretty much going to be used as a share hub at home, so 5-6 desktops. Also, I'm doing this because I need somewhere to store / access my family's media in one safe location. Thank you very much.
