I have boughten an Alienware Aurora for $3500 Canadian dollars. I am very happy with the machine. However, the manual is very vague. So I have two question. First being the PCI 4 in 1 card slot. What type of cards can i place into it, furthermore, how do I place them into it, the dummy over the door is very confusing? My next question is where does the sensor for the windows media center remote control go in the machine... and what all does the controller do?
