Hello, I recently just replaced an antec 900v2 with a CM690IIAD and i love it!! Go for the 690II!! and keep this in mind, if you dont plan on getting/changing fans, the HAF is better flowing but if you dont mind adding some fans, or getting high end fans the 690II flows tons better.HAF is limited in the aftermarket fan world, not to many options for the large fan brackets in the HAF, why I chose aginst a HAF, both case's are water friendly, 690 being more so if i remeber right(I dont water cool)
