So this was a 4 star review, but after the seller sent 2 review requests after my original review, I've dropped it to a 2 star review.  This is a reflection of the overall experience you can expect from this product.  The machine's review follows unaltered:Good, very quiet machine.  Accurately described.  However, no USB 3.0 at all on the machine.  That's very frustrating.Since there's only 2 rear card slots, that also means limited expansion ability.Still, very compact and speedy.  The machine is definitely not designed to be expanded.  While very accessible, it simply has no additional room for anything other than a slim video card.Great for a simple workstation, but I do a lot of data transfer, and it's just not up to my needs.
