Update 9/12: the code has now been used 800 times and is expired!HP.com has huge $400 off $999 desktops coupon (use code DT1158). Their loaded, high-end HP Pavilion Elite m9300t Desktop starts at $899.99 (the $150 instant rebate to $749.99 gets removed) so add $100 in upgrades, enter the coupon code and you'll pay just $599.99. I'd add the 640gb RAID 0 hard drive setup for $100. This comes with a 2.4GHz Intel Core 2 Quad processor, 3gb memory (select the free upgrade), 256mb video card with HDMI, Windows Vista Home Premium, 16x Lightscribe DVD / CD burner, HD TV Tuner (watch high-def TV on your computer) and 15-in-1 memory card reader. It doesn't come with a monitor, so check our LCD Monitor deals. The code expires after 800 uses.
