If you go to the forums there are about 300 post asking the same questions.
I would look at a few of them and then tailor it to your specific tastes. Then come back here and edit your post with what you choose and ask people for input on what you have found.
Cases are really personal preference as to what you want to look at everyday.
I mean I could post a build from Newegg but then you would change some things any way.
8 years is a lot to ask
