Okay I know this is a newbie question but the only macs I have worked with so far have been laptops with built in speakers. What kind of speakers can I hook up to my new mac pro when it gets here? I am switching from PC's and while crusing through Dell's website to make me feel better about my decsion to buy a Mac I realised in all my shopping I have never heard mention of a sound card, is this something built in or am I going to need to get a card of some kind of card to listen to my itunes while I work? I am a little ashamed to ask this question but as I am waiting for my ship date I keep thinking up all these little details. Thanks in advance.
