I'm lookikng for a cheap system thats good for a dorm room. I stumbled upon this.... http://www.newegg.com/app/ViewProductDesc.asp?description=36-121-104&depa=0 It seems pretty decent. I checked it out on amazon just to make sure all those reviews weren't biased. They weren't. This system gets good scores on every website that i found them. These should be able just to plug right into my PB right? or do i have to buy a sound card?
