Get a powerhouse HP m8100y Desktop at HP.com for only $599.99 when you use the huge new $400 off $999 coupon code DT1055 (expires 10/26; valid on Pavilion Desktops). Click here and select "Customize & Buy" and you'll find a system with an $849.99 base price. Add $150 to get to $999.99 (I'd suggest either the 3gb memory for $100 and 256mb video card for $60 or the Intel Quad Core processor for $150). Assuming the 3gb memory and 256mb video card, you'd have that plus a 2.33ghz Intel Core 2 Duo processor, 250gb hard drive, 16x DVD / CD burner, 15-in-1 memory card reader, high-def TV tuner with remote (watch HD TV on your PC), 15 months of Norton Internet Security 2007 and Windows Vista Home Premium for only $609.99. Plus, a 20" LCD monitor adds only $200 and shipping is free. When you check out make sure the following:

1. Enter this coupon code during checkout: DT1055 ($400 off $999 HP Pavilion Desktops; Note: Offer available while supplies last. Not valid with other promotions. Not combinable with instant rebates.)
