I finally convinced myself to hit the purchase button. I am a bit disappointed about the ACDs but the system will be good anyway.
So I got:
MP 2.8 octo
8800GT
Wifi
Apple care
30" ACD
Will stick 4GB or 8GB later. Delivery date is end of february
( I hope it will come sooner. Or even better that Apple updates the ACDs and I'll get the updated one
