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.
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
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.
