I own the cm 690 original without side window and there's not a world of difference between it and the advanced II... expect maybe price
cons: some of the tool-less layout is a little bit cheap feeling
attaching a fan on the side of the case even with rubber vibration dampeners causes a whole lot of noise; with the gpu area side fan installed on my case my system was approximately 50% louder at idle.. ofc ymmv
Front and top panels designed by Satan himself
pros: somewhat decent airflow and also decent cable management.. plenty of room and nice finish inside so you don't need to worry about cutting your fingers off..
plenty of other fan mounting options besides on the noisy side case mounts
pre-installed liquid cooling holes. bottom mounted PSU (if you consider this a pro)... dust filters work pretty well
unfortunately I've no experience with NZXT chassis
NZXT is higher quality but the brand is generally more expensive, what kind of hardware are you planning in putting in to this case?
Of the 2 I would go for the CM but there are better options out there.
