I purchased this to replace an older desktop that was tired.  The refurbished unit I received was clean and in good shape.  The cooling fan only comes on when I start the computer then it gets very quiet while I work.  I shopped the refurbished choices for one with a fast Intel processor and solid state drive to speed up my experience over my last computer which had an AMD processor and conventional hard drive.  This gave me everything I hoped for at a good price.  The unit I received did not have an SD card reader as shown in the photos, but I hope to get one I can plug in to a USB 3.0 port so I can have that capability.  I will purchase another refurbished computer to replace another old computer I have when it's time.
