Dell takes 25% off their most popular desktops and laptops for Labor Day. One particularly good deal is this Inspiron 580 Desktop Computer which drops from $797.99 to $599.99. Shipping is free using code ZQQZSGW6HFDG3K. This desktop features Intel's i3 processor and 6GB of RAM so it can handle several applications, and with a 750GB hard drive it can hold your entire media library. It doesn't come with a monitor, so if you need one Dell also has a deal for a 23" HD Monitor. Sales tax is charged in most states.
