Well, i have a 64bit 3000+ with 512mb ram, and a BFG overclocked FX5500 graphics card with 128mb RAM. Currently it is my somewhat noisy stationary MP3/DVD/and other media player atteched to my stero (with 3 headphone to component audio cables for 5.1 sound) In my room, i am not allowed to have internet access, but if i move it out of my room, it has to share a desk with 2 other computers, and cannot stay on all of the time (without extensive "quiet mods" and removing all of teh nice blue lights). Right now i am happy with its current position as a media player, but i am getting frustrated at the fact i have to bootup windows to use it.
I tried to use GEEXBOX, a live cd linux media player, but it did not recognize my motherboards integrated sound. So any good OS suggestions are welcome as well.
