If you're in the market for a 5.1 sound system, the Logitech Z506 sounds like it could be a decent deal at only $99. There aren't too many details aside from the price though:
We know that you'll get 75W RMS power, two 8W front and two 8W rear speakers, a 16W center speaker, and a 27W subwoofer. We also know that the system should be available in August. That's it. But hey, it's cheap. [Logitech via CrunchGear]
