After I've been thinking long, which computer I want to buy myself (it should be convenient, quiet and adequate for my purposes for the next time), I opted for the Guttec. And one thing first: it was the right choice! The computer is extremely quiet, you only hear it when it's very quiet and you listen closely. On the other hand was my old yes a tractor! The Windows registry was place on-line without problems, so that I could actually start right away. When switching from Win XP I still struggle with the installation of old applications and games, for I have indeed prof for Win7. chosen because it is easier to work with it - which is unfortunately not always true :-(. I forgive this good computer only 4 stars because the button for ejecting the CD is simply a bad design. At first I thought that would be broken, but you have to push in him far with very sharp nails, so that the contact is triggered. Pity! There was also some confusion about the memory clock. The description of DDR3 PC 1866 speech, suddenly on the invoice and on the carton dteht DDR3 PC 1600th Too bad also that the computer one day after my order 10 Euro has become more favorable. Nevertheless, I am very satisfied!
