Lian-Li PC-65; keep the front fans or ditch'em?

I'm going to purchase a PC-65 and Black Ice Extreme with 120mm panaflow fan. After removing the internal 3.5" drive rack, should I place the radiator against the dual 80mm fans or remove them and use the 120mm for all my intake needs? I'd like to save as much space as I can.

I've read mixed arguements about pushing over a radiator; especially with different fans/cfm. Is push/pull a good thing?
