Hi, I have only built 4 systems so I'm not much of an authority on computer building but the easiest board to put together has been the Asus A7n8x Deluxe. It has the dual channel you are looking for and jumpers are at a minimum, the onboard sound is great and it also loaded with extra's if you are looking to overclock, if and when you feel the need too! The manual by far has been the most informative I have seen.
