Looks like everything will work well together. I have a couple recommendations, however. Just recommendations, not changes you need to make.
1) That small mATX case with a top mount PSU is going to be miserable to try to work in. Miserable to try to deal with the long cables from the PSU; to keep them out of the way of good airflow. And the top being closed, makes it hard for the heat built up inside the case to escape. I would look for a bottom mount PSU case with a vented top. Example:

In fact, going to a bigger case would make assembly a whole lot easier. An ATX mid tower would be a better choice. Then you could look at ATX boards too.
2) Are you sure you want Win8? I tried it on a desktop build and on a MS Surface Pro tablet. Never again. Took the tablet back and put Win7 back on the desktop. Win8 is about the worse thing MS has ever done to their OS. Not intuitive at all. Like using your phone w/o a touch screen to run Windows. And I'm not alone. Here's one man's opinion of it:

There's a reason MS is allowing it to be sold below retail.
