I will hopefully soon be inheriting a Power Mac G5 to replace my aging rev. a iMac G4. Since my Apple Pro Speakers won't work on the G5, I'm looking into some new speakers (I'm assuming the one built into the G5 is no good). I don't want to pay a whole lot (probably not more than $100) and don't think I need much more power than the Pro Speakers have. Do you guys have any suggestions?
