Yiou will have to buy a set of "powered" speakers.  There's no built in speakers in PC's. 

it should have had a dell A425 set...

 

If you chose the no speaker option you get "no speakers."

BUT, when I was looking at this link http://www1.us.dell.com/content/products/productdetails.aspx/dimen_8300?c=us&cs=19&l=en&s=dhs&~page=5&~tab=specstab it shows that a basic set of speakers should accompany the computer...

I just purchased an 8300 that included speakers that I do not need. They are ADA215 Dell part number. I'll be more than happy to send thes to you for $20 plus shipping charges as I do not need them. There are also many very good speakers at places like Office Max/Depot, Fry's, CompUSA for about $70-120.

You should listen to these because the quality varies widely. I have a basic Altec Lansing system that works very well but they keep changing models every 6 months.

Sorry if I gave the wrong answer. Every time I have ordered and selected no speakers, I got just that, no speakers. I apologize if I gave wrong info. Does seem strange though. THe wording is not very clear if you get speakers when you select no speakers...

Yeah, & if you customise it, select NO Speaker option, update price, then click print summary, it will show you getiing NO SPEAKERS.  The guy got what he ordered.  DUH!
