Hey, all! I'm new to the forum, but fortunately not to MAC's. I have been wanting to hook up another screen to my iMac, but not sure what ports are all included on the back of my machine, I found out they may be vga, s-video and composite, is that right? I thought about one of the clear acrylic studio displays. I have also been looking for some Apple speakers, anyone know of any that are compatable? Thanks....
