For me I chose a 420x65 in the top because the case comes with several decent 140mm fans that you can use on it reducing over all cost. All I had to do was buy a blue led and 2 regular 140s to do push pull. I know 45 thick is reccommended but the 65 worked fine in mine.
@MrKoala I see only 8 physical attachments on the EEB and based on dimensions looks like a tight but doable fit in a Luxe. However I don't have the board in person maybe there are more I can't see from images.
