I purchased 2 of the Dell Desktop Computer, Quad Core i5 3.1GHz, 8GB RAM, 500GB, Dual 22-inch LCD for my office. After hooking them up, the dual monitors would not come on. I emailed the listing for the brand - Blair Technology Group and got the runaround. I finally asked a friend who is a computer expert to look at them. He opened the case and laughed - the RAM was hooked up backward in both towers. Way to go quality control. If you have the same issue - fix it yourself - both Amazon and Blair Technology Group will only waste your time.
