Today only, Dell.com has a loaded Inspiron 530 Desktop with an Intel Core 2 Quad processor for only $499 after a $310 instant discount, matching the best price I've seen for a Core 2 Quad system. It also comes standard with 3GB memory, a 500GB hard drive, 16x DVD / CD burner, and Windows Vista Home Premium. All components are upgradable, simply scroll across the components in the center of the landing page. The monitor is sold separately (check out recent BradsDeals listings for monitors). Shipping is free and sales tax is charged to most states.
