So, it's $0 but what do you get for $0? An OS that can play only Linux games as well as your existing HTPC hardware allows (do you have a Linux distro on your HTPC already? if not, why not?) and the ability to stream games from another part of the house, which would make your gaming machine pretty much unusable for work during that time (again, just run a HDMI cable and USB hub alongside your network cable and you won't even need your HTPC for gaming). If you really needed to stream games from another part of your house, you would have done it already.
