Well the Thermaltake Armor is a very nice case. Gives me old nostalgia of when cases were made out of more than just tinfoil.
But for the best bang for your buck, the Coolmaster Centurion 5 comes to mind. A very nice case for the price it's offered at.
With a case, the best piece of advice is get what you like. Don't be persuaded by what others say. Get what you like the look of.
I personally have a Tt Kandalf (same as the Armor but different front) and love everything but the cheap plastic on the top around the USB cover.
I agree, on both counts actually. Look around for a case that looks appealing to you and has decent airflow. There's a lot of options for you, and there's not really any ONE case that has the 'uber' airflow.
I also don't like those ports on the top of the case, I just ended up taking them out all together to get rid of some of the wirey mess at the top of my case.
