I have written about Boxee and some of the things I have done to set it up at my house on my HTPC.
Recently, I read that Boxee was not going to be developed any more and so I felt the need to upgrade my little home server.
I wiped out Windows 7 and installed Linux Mint 13, after some struggles getting the sound to work over HDMI it worked perfectly. Installing XBMC is pretty simple and as easy as choosing it from the software manager.
There are two features that I absolutely love about XBMC, the ability to stream videos over airplay and the remote I have installed on my Samsung Galaxy Note is full featured.
If you need help setting it up drop me a line in the comments.
