There are brackets to mount a 240 rad on top of the phantom, and there are holes in the back so that you could mount the radiator on the outside back of the case. I modded my phantom to fit a 240 rad on the inside bottom of the case, theres lots of info on that mod if you look around. I love my phantom.
Both great cases, either way you cant go wrong
I know that you can fit a radiator on top of the phantom, but is there enough space to fit a thick radiator such as the XSPC RX240 without the motherboard getting in the way? I have low profile ram, so that wont get in the way as much as the motherboard heatsink would...
