The CM 690II is the better case! even the basic is better.
Wider so it's easier to choose HSF,bigger so there's more room to expand and work in.
Higher quality construction.
Great design and airflow options.
Cm690 is better for cooling I have used both of them in my fathers shop, I would recomend both tho the only thing bad about the cm690 is you need to buy a bunch of fans to fill it up. But just go ahead and by the cm690 it's the better deal just buy it and something else from tigerdirect.com as long as you spend over 100 bucks you get free shipping.
