I was a bit skeptical when buying this, but based on reviews I went for it.  It arrived quickly and well packaged.  Specifications are exactly as described and there are no cosmetic issues. Computer is completely silent and extremely fast.  I activated Windows 10 Pro, installed a few updates, installed Microsoft Office 2019 and its running perfectly.  I added a second 2TB hard drive for file storage and backup and there were no issues.  If you're looking for a cheap option to upgrade your home or business computer, this is a great way to go.
