I had a set of the Bose Companion 2 speakers, had issues with a humming sound when there wasn't any sound. As far as looks, the color of the aluminum wasn't a match - though I wasn't going for look as much as sound quality.
I did however return them due the buzzing noise, I picked up a set of the Logitech Z230 2.1 speakers. No buzz, and the aluminum matches very well with my iMac and Macally external drive.
