Like almost everyone else on the planet, I don't leave reviews unless something REALLY pisses me off or blows me away at what an incredibly good deal it is.  This one blew me away, I am amazed at what an incredible deal it is!  I hate buying used electronics since its such a crapshoot,  you never are sure what you are going to be ending up with refurbs from office returns.  This system looks brand new, not even a tiny scratch that I could see, virtually zero problems at all.  The seller included a keyboard, mouse and a wifi adapter that was not in the description so that was a pleasant surprise.  To be able to get an i7 system with 32gb RAM, a one freaking TB SSD drive and Win10 pro for under $500 is an amazing deal.  Beyond pleased!!  Although one thing is really ticking me off, I'm kind of bugged that I can't justify the need for another one :)  Go ahead and buy it, you won't be disappointed.
