First review! As expected Windows is in German, but this is easily changed when a language selector appears after a few screens. It is fast, reasonably well built, and yes it is much quieter than most PCs. There is a Windows 7 recovery disc supplied with some other driver discs. Also there is a setup manual with a section in English, so that was welcome.
Regarding the 2 year warranty that is stated on Amazon that CSL gives you, there is no written warranty supplied in the bag with the discs and manual. So I contacted CSL through their (German) website, and they responded saying that as Amazon had delivered it in this case, if there was a problem in 30 days to contact Amazon. Thereafter contact CSL, whereupon they cover all defects for 2 years as long as the PC is used as intended. They send a label to return the PC to them in Germany for repair if needed and ask that the original boxes are retained if needed. I would like to suggest to CSL therefore that there should be a written warranty with the computer, or perhaps some other means for customers to register the PC with them as purchased and the date.
However, I am optimistic that all will be well with this PC.
If I have anything to add to this later, I will do so, as this is only day three with it and CSL!
Amendment 16 April 2014
I made a few detail amendments to the above to include the 2 years. I'm also very pleased to report that, since I originally wrote the above, CSL have, in response to the above I guess, sent me an Invoice, detailing the computer, it's operating system and components, also stating the two year warranty. It is mostly in German, but Google translator helped. They also sent their Terms and Conditions document, in German. But I got it translated online.
As of now I am very pleased with the computer and would recommend it.
