Replaced the 512 GB ssd drive with my own 256 GB ssd drive that had Windows 10 Home on it.Reformatted the 512 GB drive and now using it as an external Backup/Storage drive using a usb to sata cable that I had.Clever case design uses no tools to open it and remove the internal ssd drive.Came with a usb wifi dongle.  No bluetooth. Will have to buy a bluetooth dongle.Works well, no noise. I use the computer for web browsing and Office apps.
