After building the new desktop system, the old computer still has enough hardware to be used, so I would like to find something to install to it and use it as a media box or gaming machine for mother.
GeeXboX seems a good choice, it is a live CD for media player, like songs, movies.
Another choice is Advance CD, which is Advance MAME live CD, which is used for playing games.
See if I have time to build it next week.
