I am just wondering if these speakers (Amazon.com: Logitech Z-5300e THX-Certified 280-Watt 5.1 Surround Sound PC and…) will work on the new iMac 27"? I will be purchasing the iMac 27" soon and want to know if these speakers are compatible with the iMac 27" or if I'll have to purchase new speakers. Thanks! Also if these speakers are not compatible, would someone please point out some affordable speakers that are on-par or even better than these? The speakers I have (check link above) a three-prong cord that hooks into my computer. I just checked out the iMac 27" ports and it doesn't look like there is a three-prong port that would allow these puppies to work. Could someone help me? Sorry for any confusion.
