an Nvdia or Ati graphic card,those with the top blocked by the casing is easier (Y) )

How to do:
Download a picture of a prefered graphic card
Follow the shape of it
Fold the cardboard,do not cut parts of it and glue it back
Cut 2 sides of the fan(do not throw away the sides/pillars)
Connect the wire together(solder them,I tied them together)
Check where your vent and usb is situated on your laptop
,and follow along(Cut the flap where the vent is and poke the usb through where it is)
Next is to leave the other side closed and add in extra details,paint it better
Then you shall have a GTX 470 for your LAPTOP and it its not only nice looking but also usefull
