Hi, i thinking of buying haf-x but there somethings i must know ahead.

1,i need some forumer's opinion about haf-x.
2,perhaps some cons & pros for this monster.
3,also, i would like to know what kind of fan good for this casing.
4,finally, i wanna know if the red led fan in front can be change?

Hi, thanks for the quick reply.
1, why does this casing get dusty easily? i mean from what i seen, it has a lot of dust filter.
2, what kind of fan i can change with the front 230mm with? does LED on/off switch still work after the change?
