So far, I am extremely pleased with this purchase.  The unit arrived in about 5 business days.  It was well packed.  the keyboard and mouse provided were of reasonable quality.  The machine itself had one minor cosmetic blemish on the right end of the case.  It appeared that the previous owner put a sticker (dontcha hate it when people do that) on he metal surface which left a minor dull patch about 3 inches across.  Since the box sits under my table, it's no big deal.Everything else works great.  The machine itself is faster than my two 3.4 GHz. I7s at home (think they don't have the 3.9 turbo boost feature).  They also don't have SSDs, which also accounts for the peppy performance.  My unit came with Intel 4000 integrated graphics, which I'll assume is "better" than the 2500 advertised.  The only disappointment was that the Amazon ad had a big WiFi sticker on it.  I read the details, didn't see WiFi, just saw "connect with wires Ethernet".  So, I pre-ordered a $15 WiFi dongle so I wasn't too disappointed when as expected, this machine had no WiFi.All in all, this is a good deal on a pretty nice system.  Highly recommended!
