The PC didn't even boot up into windows 10 pro it was stuck on a test screen. I used my own usb boot disc to get the pc to go into recovery mode  and after 2 hours of trouble shooting I got it to boot up and into windows! But it gets worse! The image of windows was windows home edition for an Asus computer... when I tried to change to the provided Mircosoft product key it didn't work. I called the CNB tech support number 5x and after sitting on hold for 20 minutes the calls magically dropped and all subsequent calls went to voicemail due to the limited hours of tech suppprt. The only tech support or instructions you get is a two sided instruction leaflet that might as well been written in crayon!The PC was well packaged and the hardware appeared to be in good condition. There obviously wasn't any quality control prior to shipping the PC out. I packed the POS back up and returned it ASAP.I simply can't recommend this seller/vendor to anyone!
