There are some more questions in there. I'm not too sure how the xbox works on a network, but I'm pretty sure that it required a windows os. If your using a PS3, a linux based OS would be better.
If you are sending data over the network to be played on your PS360, the current generation CPUs, RAM, Video card, sound card won't affect anything (someone correct me if some of these are needed for video playback on a PS360?)
