This is an excellent value for my immediate needs.  I added a 500Gb SSD and with it's 16Gb memory it is a very responsive system.  After seeing many reviews expressing disappointment in the condition of the system received I chose a Microsoft approved refurbisher with 99% positive reviews.  Maybe this was prudent shopping, maybe just being superstition but lucky.  But my system was just what I expected.  Three memory sticks were one brand, one a different brand.  But memtest86 ran 24 hours with no errors.One star is deducted because Amazon and it's vendors were not forthcoming about incompatibly with Windows 11.  They surely were, or should have been, aware of this.  Boo to Amazon and vendors for lack of transparency.  Boo to Microsoft for reneging on their promise to support Windows 10 forever (some might call this fraud).  Boo to the American consumer for putting up with such shady business practices.
