Speakers for G5?

So I have this 1.6 G5 now with optical audio out. Anyone have any recomendations for speakers? Maybe the Logitech Z680? I'm thinking about using the G5 as my entertainment center instead of a Denon receiver, etc.

I'm using the Logitech Z-680 using the monster cable, for the optical port. All I gotta say is that, the sound is amazing. The woofer shakes the entire level. I'd definitely recommend it, on the G5. Btw, make sure to put sub facing a corner so that you get the most bass you can get.

=-)

just bought bose companion 3 pc speakers and they have great sound for $200 at best buy. will not shke the building though but have a subwoofer and tiny great sounding satellites.
