Then bought a big screen TV for it.
Problem: The TV does not have a VGA port for the computer.
Solution # 1: Buy an Android tablet with an HDMI out. Use VLC to stream content from the Linux Box media centre. Watch content on the big screen TV.
Solution # 2: Buy an Android tablet and NSA. Connect the two together. Watch content on the big screen TV.
The real irony is that Android Gingerbread is a better server than Microsoft's Home Media Server 2011 is. (Fewer bugs, and more out of the box functionality.)
Coming soon to a tablet near you: AAMP.
