The top only supports 120mm fans because 360mm radiator means 3 120mm fans(120 x 3 = 360) and the NZXT Kraken X60 uses 140mm fans, so it won't fit. If you look at the compatibility list of the X60, the HAF X does not support 140mm at the top.
Very well explained , thank you = ).
Maybe cut back on your power supply you can get a decent one for about $80- $100 bucks less eg Rosewill hive 750w modular http://www.newegg.com/Product/Product.aspx?Item=N82E16817182133
$90 -$20 promo code(ends today 3/1)=$70 which is a savings of $130 over the Seasonic
and get a different HDD eg Seagate Barracuda STBD2000101 2TB 7200 RPM 64MB
http://www.newegg.com/Product/Product.aspx?Item=N82E16822148910 $110 savings of $80 over your previous choice
With the $210 saved get an Ocz Vertex 4 128gb SSD($110) and the Kraken X60 which is $50 more than your X40
