What are some really good cases for around $100?

I'm not actually planning to build until next year when i have more money. But my wife is planning on getting a case for me. I was thinking of getting a full or a midsize tower. Ive been looking at a few cases Like the rosewill thor v2 which is at the upper edge of what she will be able to spend. Airflow and noise are big concerns.

 

The NZXT phantom 410 is a really good mid tower that comes in many different colors for just about 100 bucks

 

Fractal Design has quite a superb case selection for around there. http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007583%2050014581&IsNodeId=1&bop=And&Order=PRICED&PageSize=20

Fractal Design, Bitfenix, Cooler Master has some good airflow cases in that range.

I'm going to be building my PC later this month. I still can't decide between the Gunmetal 410 and the Define R4 with the titanium front and side window.
