Computer was delivered and that's about the only thing that was right. Unpacked and NO POWER SUPPLY, NO WIFI Antenna. That's really all I can say, because could never fire it up or anything else. I promptly returned it and will not buy from  SKYTECH USA LLC again. Also I thought the shipping packing was poorly done for something with a heads/mechanical hard drive inside. Now I have to pack it up and take to the UPS store. I'm disabled and this has been a big waste of my time and energy. I can not express how disappointing this experience has been.
