I just noticed they now have the HAFX "Blue Edition" All the fans have blue LED lighting
Check it out here
This is alot like my HAF932 "Blue Edition" that I have.
Hell I would just get a Blue themed Advanced and buy Blue Yate Loon fans to fill out the spots that lack blue and save a bit of money.
It costs a bit more if one is set on 200mm LED lighting features but if you can get around it, that's how I would go about doing it.
