I am a vine reviewer, but I paid for this product.UPDATE - After contacting seller they quickly sent out correct video card and caddy.  I raised my rating by 3 stars to 4.  This computer is a beast!Originial review-Received the Z620 quickly.  However, upon receipt and opening the case was pretty severely beat up.  Many plastic parts, both trim and framing were broken and missing.  Internal was very clean, but it was missing one of the internal drive caddies.Was advertised as having a Quadro K600 video card, instead it had a cheap Radeon card.  I noticed from other reviews the seller has done this on others.  This is just wrong.  If for some reason the listed video card is not in the computer, then ask the buyer if they want a cheap, less powerful one.  If you decided to remove one of the 3 drive caddies to possibly sell separately, then ask if it is ok to not send all the components.  And yes, this missing drive caddy problem exists in other reviews.The computer runs beautifully. However, I'm now having to buy a decent video card.  I guess I get to buy another drive caddy.  I guess I should not be concerned that the case looks like someone beat it up with a brick.  Oh, and don't advertise that it is in excellent condition from a foot away.  That might be true for someone that cannot see.
