Putting 2 led fans in the front and 1 in the top vent make this case look very nice without being "too much". Only 2 things I find inferior to the older version, one is that the plastic trim on the front has sharper angles where the older version was uniformly rounded (I bumped my comp chair against the edge and marred the trim within a few hours of setting it up, this never happened with years of use with the old rounded version. Second, the new fan mounting system on the front is definitely a step down from the old version which has a steel cage enclosure while the new just gives long screws to attach to the front. This seems to create a situation where you fans make a harmonic vibration which increase noise. Both fans have the rubber insulaters to inhibit vibration, I also switched the fans with the older version and the older version remained silent and the new case was just as loud so it was in no way a fan issue. I still like the look and the noise isn't that bad and isn't a deal breaker but had me concerned until I tracked it down to a case design issue...
