No, a single 240 isn't going to cut it. I also don't think you are going to get them in there, sandwiched, either.
There appears to have been a trend lately where folks have bought cases and want to shoehorn a complete water loop inside, only and there's barely enough room inside to let light in with the case open.
You're going to have to get creative on this one...mounting on the back or sides is your only other option, or build a pedestal for the rads and pump, etc.
