Not sure what your question was.
I just built my first, just go slow, its a little intimidating. I just followed my Asus manual, kind of outlines the process. If you don't understand something, re-read it, google it, make a forum post =), etc. Just make sure you understand what your doing and you will be fine. Good luck!
I got a static wristband from Radio Shack for like 5 bucks due to pure paranoia...
make sure you install the stand-offs. They are little screw in thingies that go into the case under the mainboard and the mainboard screws go into those.
