I am currently exploring all options for the purpose of a media server as I transition from Windows x86/x64 hardware to Apple materials. One item of concern is revamping the media center from Popcorn Hour with DAS storage and integrating Time Machine support as much as possible. One option involves using the DAS with a Mac Mini, but I do not like the idea of having extra hardware laying around the living room. The second option that I like much more is using a Mac Pro as a VNC machine. That said, I am uncertain on my understanding of options and necessary hardware. I would like to have a Mac Pro 1.1 tucked away in a closet with a few large 3.5" drives installed internally, and the system ran as a VNC. If I shared the optical drives and hard drives on a network, could I then... Share the optical drives to a MBA and rMBP on the same network? Use the Mac Pro internal drives as Time Machine destinations for the various hardware on the same network? Use software like AirParrot to play ISO files on various ATV3 units? Lastly if all of the above is true, and if I am running the system only as a VNC, would I actually need a video card installed in the system?
