I was anxious about a refurbish but so far it is working fine (one day since set up).  The price was so low and even included an unnecessary mouse and keyboard which seemed too good to be true.  I think the reason for the price is that it cannot be upgraded to Win 11 which is fine with me.  My techie sons told me not to get Win11 and this refurbish was the only way I could get Win 10.  I will miss Win 7 but not as much as XP, but I will adjust.  The tower is in excellent condition and has what I need to do what I do (not a gamer).
