    • Disappointed!
      Verified Purchase

      I used this item for thirty days and it started acting like doing it's own thing. I had antivirus protection on it, come to find out the hard drive was messed up, unfixable and I had to send it back. It was refurbished. I had to get a brand new computer. My refund was given and I am grateful for that.

      I needed a Win 7 machine and found it here at overstock, I'm a Dell person because of their support and abilities for restore disk(which i have). but this unit was to be purchased with a 750gig hd and it came in as 1tb(cool). windows 7 (FRESH) ready to be installed! all went perfect. I love the No SHIPPING cost! would purchase again

    Questions & Answers

    • Q:

      "My order does not come with an installation disc. Is this disc necessary and can one be purchased from overstock?"

      • A:

        Hello sannamaed1, this does not come with the CD. Microsoft Windows 7 Professional should already be installed on the system. Have a great day!

      • A:

        will monitor and printer from Dell computer work on this set?
