The storm scout is 80 on newegg after rebate and uses drive rails (yuk imo) but I do like the angled front panel connectors
the 690 II is also 80 on newegg after rebate. It uses drive trays (i like) but I dislike the top mounted 'front panel' ports. They would not work for me as I do need them on the front.
So now that there is no price difference, get what works best for you.
Thanks. It's a difficult decision, can you give me some other differences except the size? I actually can get the storm for 70, but I'm a little bit worry because it has smaller size and can have problems with airflow or/and with big GPUs. Am I right about it?
