Hey Everyone!! I have 2 Macbooks and 1 PC all laptops. I'm interested in setting up a server to store images, videos and business docs and have them sync with the computers wirelessly. I thought the cheapest method is to go buy a new cheap $400 PC from Walmart and use that as a small home server. What server software should I use that would allow both PC and Mac to connect. Also, whats the easiest to use? Looking also to include a backup HD for double backup of said images and vids. Looking at Ubuntu, but really as you can tell have no clue.
