1. the option of using a 32GB SSD instead of ram, it will use less energy take up less space and make less heat leaving room for... 2. upto 4 Nvidia Quadro FX 5600 (BTO, naturally) or Nvidia 8800GTX (8900?) 3. Blu-ray/HD-DVD drives (choose which you want or have one in either drive bay) 4. 1TB HDDs (cause they have them out in 3.5 inch enclosures) 5. 4 Quad-Core Xeon Chips...or maybe 4 CELL processors (if you want to be ridiculous, or just bring back the POWER series-based processors) 6. RE-DESIGN and I mean a REAL RE-DESIGN not the new iMac style redesign. 7. some extra PCI-X areas for whatever.
