I bought this HP as a clone backup to my other HP Elite 800 GF, having recently recovered it from a crash on the HD caused by Norton.  It was in excellent condition as refurbished and it booted up right out of the box with no problems at all.  Just signed in with my Microsoft account and everything loaded without a hitch.  It takes a bunch of time to setup the updates and such. This is a great little desktop and has like 4 slots for cards that I don't need as I just use word processing and basic video watching.  My first machine was also refurbished and has lasted more than 3 years so far.  I am sure this one will last too.  Bring on the next crash and my backup machine is ready! Refurbanana is a great outfit.
