The desktop computer arrived today but it would not boot.  The monitor connected to it kept reporting "no signal".  I tried display port cable and then VGA - same thing.  The power button on the desktop kept flashing yellow.  Also, the computer was making a loud noise.The customer support phone number for SKYTECH USA sends you to a voice mail box.Returned it the same day.  This cost me a couple of hours of work: removing computer old computer setup, replacing with new, then doing it again in reverse order,  packing the return box, and driving it to the Amazon store.In the future I will watch out for the name SKYTECH USA and avoid them.
