Summary: This computer kept shutting down for no reason. Contacted customer service and tried several things till it was decided to send back. Overstock.com was very helpful with the process. Got credit back on CCard and have them sending me another model.
Summary: Unfortunately the PC wasn't fully tested b4 sending out, it will shut off after a while on. It looks like overheat easily. However the service is excellent with full refund and no any argument.
Pros: These are used machines, and most likely off-lease after 3 years of use. These should be marked as "used" instead of "refurbished". My power supply failed after 3 days of use and cost $36 to return unit (20 pounds to CA via UPS Ground is not cheap) You might have better luck, as my experience with other Dell new OptiPlexes have been great. But in my case, the product failed.
Cons: Product failed. Product was already end of life cycle, didn't realize I was purchasing a machine already used for 3 years in field.
Summary: I got it setup and it was fast, I was loving it, then 4 hours after I was surfing the web it crashed, and it say "Video Hard Drive Error". I went on google and it said I need to update the drivers. I updated all of them and still crashed. I lived chat and got a replacement one, and the replacement crashed too after 4-5 hours... I'm upset because the specs were so good for the price.
