I know its really popular to connect up hifi systems to comps, I'm currently hot swapping between my 5.1 Phillips PC speakers and my Sharp Mini hifi - but what about the 5.1 home cinema speakers you can get?

Those two are only examples but I'm sure you get what I mean. It seems like no one has thought of connecting a system like that rather than a proper hifi or proper PC speakers.
