This is proof that it can be done, and done right, the first time.
I'm still amazed at the troubles people have getting the first successful boot from a new build.
I'm of the school that says, "do as I say, not as I do", which means, that I'm the sort that stuffs everyting in the case, and hooks it all up, and then hit's the power switch. Not really the best way to do a build, but I've rarely had one fail, and it's usually because of a faulty part, not the way it's built.
There is no magical formula for building, and it's not near as complicated as people think.
The single most important tool one needs, is patience.
Congrats on the nice build!
