I was excited for this purchase - it is a very good price but remember - you really get what you pay for - not just in product but also experience.I needed this computer for CAD (Solidworks) and Rendering. The type of work I do requires great speed and accuracy so I needed the exact specs stated on the description. I hoped that the experience would be seamless and I would be able to just boot it up and work away, but that was until I received the item.When I received the product, I had a handful of concerns:1. What I received was pretty banged up - a lot of pretty deep scratches on the panels, 2 missing rubber foot. I didn't make a big deal about this but I have to be honest that it did lower my confidence of the product. I bit the bullet on this one.2. Also, what I ordered was a T3600 but I was confused because what I received was a T5600 - Sure I should have been happier that I received a "newer" version but it created a lot of confusion and back and fourth with the seller to figure out if the specs were the same.3. Because I received a different model, this made me lose some confidence in the product even more! I went ahead and checked thoroughly that the specs were correct by opening up the computer to double check the parts. The second I opened up the panel I already saw that there was a discrepancy on the video card - The description says NVDIA Quadro 5000 but what I received was NVDIA Quadro 4000. This was the ball dropper and I was about to just return the thing but the seller was nice enough to offer me $125 back so I kept it.4. In addition, the description was not clear if this machine had wifi or not. I assumed that it had wifi since it didnt say ANYTHING at all about not having wifi built in - until I received it. I then had to drive to Fry's to pick up a USB wifi for $30.My whole experience with this product and seller was just a big hassle. All in all - if the seller were to just give me exactly what I paid for, none of this would have been a hassle.  Other than that - the computer was very well packaged and does work after all the extra things I had to do.So here is the lesson - you really get what you pay for. The price helped and the seller was nice. But the time lost in this whole ordeal was definitely annoying.
