Most motherboards have several connectors, so just look around where the others are connected.

BTW, to comment on what others have said above: Definitely run WOW from the SSD. I have a Samsung 64G SSD and it's amazing. The only thing though is that I also mapped my virtual memory to the SSD and I think that might have been a bad idea. I've been getting lots of computer hangs and I think that this is the reason.
