We purchased this because we thought a power outage fried our other Acer. Our original tower came back around to good working order in a few days.  My problem was we were credited back only 2/3 the cost of the tower. When I first set up the return we were told we had to pay the shipping and it would be deducted from the credit.  They also tacked on the cost of shipping to us and a restocking fee.  If we had knot that we would have kept the Acer as a spare.
