Bought 2 of these form this seller.  First one failed several months in when the PC no longer acknowledged that it had a DVD drive (It had only read 6 or 8 CDs at the time.).  Put a DVD/CD in the drive, close the door, and nothing.  Thank goodness for Assurion.  Got my money back on that one.  Turned around and bought the same machine again.  On this one the DVD drive also failed, but this time after reading only one CD.  Heck, when I unboxed the second machine it had a previous owner's DVD of a "Magic Schoolbus" game in the DVD drive (so, we'll chalk that up to poor quality control).  When it did read the one CD, the drive sounded like a poorly tuned lawnmower with an unbalanced blade.  The entire case vibrated as the machine struggled to read the CD.  Time to find a better seller of refurbed PCs.
