Its an option, the reason I wasnt going to was that Live wouldnt allow me to run Sickbead, CouchPotato, SABnzb etc. However I have noticed that XBMCbuntu might allow all of the above.
However, since I've already spent the money, my plan is to separate my server functions from the media player ones. Have the larger and louder HP away in a cupboard somewhere and a slimline media player under the tv with no other responsibilities, hopefully a rock solid media centre.
they do run on live - swap shells with ctrl 1 to 4 & startx for linux gui
