Looks like Dell took it away. It was there just a week ago. 
Anyways, here's what you still CAN get: 
-Intel® Core™2 Quad Core Extreme QX6700 Processor (2,66 GHz, 1.066 MHz, 8 MB cache) 
-4.096 MB [4 x 1.024] 677 MHz Dual Channel DDR2-geheugen  
-1TB Serial ATA RAID 0 Stripe (2x500GB 7200rpm drives with DataBurst™ cache) 
-16x DVD+/-RW- & 48x CDRW/DVD-combinationstation 
-DUAL 768MB NVIDIA® GeForce™ 8800GTX graphics cards  (strangely, that's the only card they have for that PC) 
-128MB Ageia™ PhysX™ physics accelerator PCI card 
-Sound Blaster® X-Fi Xtreme Music PCI-sound card 
-No speakers (I just choose this, you can get quite a variaty of speakers) 
-Logitech Cordless Desktop MX3000 Laser - VS Int. (QWERTY) 
That for € 4.829,69. What is about $6200 USD. 
Edit: and some strange H2C cooling system. What ever that is.
