Purchased this unit a few months back.  I should have tried it right away so I could have returned it.  When i booted the machine for the first time to setup windows the system error out when it asked for a "language".  I selected "English" over and over and continue to display message "something went wrong".  I'm an IT Program Manager and these problems never happen in systems we buy from US companies like Dell, HP and other well known companies.  Everything was in Chinese.  For most people trying to setup you would probably toss the system against a brick wall from frustration.  I painstakingly booted up in chinese and hoped i answered the questions correctly enough.  I also had to reset CMOS twice and start over but i finally got it into windows  "Chinese" language.  I then went into the control panel and set the language to English as default.  There were a few other items i had to set to remove the chinese language.  I finally got it all to work.  Total time wasted was 4 hours.  Should have taken 20 minutes or less.Suggest everyone before buying these units from Chinese companies to see if they have US tech support and not international phone number.  No one answers on the other end.  Just window dressing to make it appear they have support.The product is not bad if you want to waste valuable time and get a few more grey hairs, lol;
