The Antec DF600 Flux is quite the conundrum. On one hand, it is a solid choice with a very sturdy and functionally well-designed frame. The inclusion of three magnetic dust filters and a pull-out one on the floor is rather unusual with a $70 case. The same goes for the included Velcro strips and sheer number of fans. As a well-designed case, the Antec DF600 can also hold a very good number of drives without compromising on any cooling elements, like additional fans or radiators, all while including USB 3.0 and a beautifully clean window.
It sounds like Antec got everything right with the DF600, especially as they include five fans right out of the box. That whole feature set reads like a dream come true and can generally be considered unmatched for a chassis of a mere $70. That is, until you are abruptly brought back to the reality of things after turning your system on for the first time. The sheer noise level shows that Antec approached cooling with nothing but brute force. Their reversed fan did not really help make a dent in our testing, either. While we usually are fine with louder fans as users can adjust the curve to their liking in the motherboard BIOS, the DF600 Flux provides nothing for you to do so. Instead, you are left with a fan hub with nothing but the ability to drive these at full speed all the time. The DF600 Flux will remain uncharacteristically loud for an ATX chassis of this day and age even if you have five fan headers on your motherboard.
This is absolutely unfortunate as the Antec DF600 Flux is otherwise such a nice and feature-packed chassis that I would just want to skip out on all the fans and the PCB for good measure, to buy it for $50 and spend another $35 on a triple-fan and controller kit of my choice instead. That having been said, the Antec DF600 Flux will still provide quite the value for your money if ultimate cooling trumps noise for you.
