This deal has ended.
So Dell.com has this Inspiron 531 Desktop for $499 after a $100 instant discount. Good enough deal as is. But add $400 worth of upgrades to get the base price to $999 and you can enter coupon code 4J1M7748R2RRV6 ($350 off desktops only through 11/14) and pay $649, only $150 more. If I were you I'd add the following and get up to $1004 before the coupon and $654 after: the 20" Samsung LCD monitor, 2gb memory, 500gb SATA hard drive, 16x DVD / CD burner, 128mb nVidia video card and the Integrated Soundblaster Audigy. With the included dual-core AMD processor, this is a powerhouse with a great monitor for just $654! Shipping is free; sales tax is charged to most states.
