I sent Corsair an email about the space between the motherboard and the top of the case to see what you could fit, and they said:
"I measured a case which has the EVGA X58 motherboard installed and there was 10-10.5 centimeters between the top of the case and the top of the motherboard."
Which gives you enough room for a BIX and 38mm fans!
