Oooooo, just what I have always wanted, a clear expansion sleeve. I don't know why I have a think for seeing the insides of comptuers (not like you really "see them work"), but this looks rather fun. It's a clear CF expansion sleeve kit (take the hardware from yours put it in the clear one), and I think it says it is only 4980 Yen (which would be less then $40 USD...$60 to our good friends in Canada). I wonder fun they sell to people in the US, cause I wouldn't mind picking up one of these.
