Order had to the PC a second time, because the operating system (Windows 8.1) not allowed to start at the first copy - despite the quite friendly assistance by a CSL technicians. (Thank you!) Accustomed quick and easy return on amazon and receive a new computer (this time also saw the front of as if it were new - the first had a few scratches).
Computer is extremely quiet and fast. I like it very much. Does what he should. Image editing, video editing, office applications. Am thrilled.
