For future readers, please list your specs and then the links underneath them. It was a pain clicking all those links just to see your specs.
Anyway, everything looks good. You may want to consider 2 GB of RAM though.
This is my first build, so how's this for a case?
That case is as good as any for a first timer, except maybe a huge case with a removable mobo tray
