All computer sold with their unique service tag letters numbers and the rigid test had the same tag too. This computer bought from auction over 4 years old and during these time been in storage and finally got time to do the listing.  Although you see the production date is 2011 but at least 4 years + 2 years time during auction freezing period so the computer the most use is 4 years.  

I spend over an hour to refurbished the computer including air dust inside out all fans, cpu, case inside out.  I install extra SSD drive which you boot up computer to screen in less than 10 seconds.  Install genuine windows 7 pro with service pack 1 and you can install updates later and I also double check making sure the components passed the rigid test.  Also install all drivers with original Dell cd and not from website download.  All these are taken in pictures for you to review.
