Pros: well-made sturdy housing, super quiet, top cable management, sufficient connections: Mainboard 20 pin +4, 2 x CPU, 1x PCI Express, 4 HDD, FDD 1, 4 SATA, 4 FAN, Cons: the first device of this infamous E I have returned because nothing was more again after 6 months 5 Series. Have Sustainer kill also via DHL exchange box within 48 hours free replacement. So here also good servcie. Then the whole of the computer was now three years well until suddenly no longer ran high. After I pulled the mains plug from the power supply and plugged in again after 2 -3 minutes, he ran back up. This procedure, I have to carry around another 4 months at each start-up until then suddenly again nothing went. Internet search brought me to the realization that just the E 5 Series massive problems related to longevity has. Property me now nevertheless again Be quiet Nezteil ordered, the E 8 series, I'm really curious how long it keeps time. As for the smooth running and the voltage supply (even with complex 3 D games), I am fully satisfied with Be Quiet. Even smell is a foreign word in this Neztteil. Only 3 stars gibs for the now well-known aspects of longevity.
