For me, unfortunately, is rather disappointing, because the volume of the system is still (for me unacceptable) is high. On my computer the noise level was always the same (immediate startup, then Windows without opening applications) and was not higher while playing. Playing is the noise level thus perfectly fine (and probably even relatively quiet), but if you want to work or the like as is the fan noise but clearly disturbing and I wonder what needs to be there so vigorously cooled. The fans do not seem runterzuregeln anyway.
From the speed of the machine is very good, except for the hard disk, which slows the system slightly and some slow RAM. Tested game (ARMA 2) ran with me but very satisfactory. Nevertheless, from a whisper-quiet system in this price range I expect simply more. Therefore only 3 stars.
