I am surprised to read all the negative reviews! I have had my current PowerSpec 8923 for four years with no problems at all. It is running at least 12 hours a day on most days. I had another one before this and it was running strong for the three years I had it until I foolishly decided to go with Compaq simply because I liked the looks better- big mistake. I plan on buying a new PowerSpec soon. The reason I got PowerSpec to begin with is because a friend in another state who builds computers said it was a decent brand. The Compaq I had died shortly after the warranty ran out.
