I'm having trouble finding much information about that case.
From some pictures I could find, a double radiator would not fit. A single might.
If it's the case I'm finding and you're having cooling issues, you may want to consider getting a new case first. You can get a case for the same price that will have a much better stock air cooling system.
I guess a good answer here would really depend on what problem you're trying to solve but at any rate, no, I don't think the Antex X1-E would fit a double radiator water cooling system.
