Unit is in, like new, condition (I would say it is a Grade A refurb).  ONLY reason I'm not giving 5 stars is that when I unpacked and powered up the computer... instead of just booting right into Windows 10 to be configured... it kept booting up into GRUB(?)!!!  WHY would a computer that is supposed to be setup for Windows 10 Pro, booting up into Linux GRUB?  And HOW did it leave the seller without being properly tested.There was no way around it so I had to wipe the drive and reinstall a clean version of Windows 10 Pro.This is NOT something a "regular" person would do, but I've been working with computers since I built my first one (Altair 8800B) in the 70's.  But then again, a "regular" person probably wouldn't be buying a refurbed desktop computer either.
