Dell refurb computer by Skytech USA initially showed much promise as it operated very well.  However after a few weeks one day would not boot up.  Diagnostics revealed the Hard Drive was not operational.  Further testing confirmed it was dead.  Skytechs answer is crossship a new HD.  I will not return a dead HD with all my personnel data to unknown tech people.  A 1TB HD is relatively inexpensive.  I will replace the drive myself.  I would not recommend any refurb system from Skytech!
