I am looking at these two cases. I am interested in the Obsidian 550D and the Black (only) NZXT 530. Both are excellent for different reasons, so which one should I get. I will mostly be using headsets while playing and am making it mostly with MSI red/black components. What will give me the best performance in the terms of esthetics and cooling.

Any opinions welcome, I know that all of my components will fit and work in each.
