The top chamber can hold 3x120mm fans but the best you can do is 3x single 120 rads and not a 240 or a 360 single rad. Reason being is you know how the radiators stick out a bit for the hose nozels? There's solid pieces of metal blocking the very left and right side of the chamber so the hose nozel has to face towards you (Alienware sets up their default 120 rad like that) you also need a 38mm thick 120mm fan for clearance purposes. I hope this helps.

Seriously? I'm sure I saw someone on the forums who said you can add one of the 3 fan rads that XSPC sell... What mods can be done to correct this? A riser or something?

You can add one so long as it is a single thick rad

You can use a tripple rad with thickness around 30 to 45cm. It's very important to note that if you use 38mm Fan, you ain't gonna need to do any mod to the cage.

Right. Because the 38m fan will then screw into the tray. If you use a normal fan then there is a gap. If you use a double thick rad then there is no gap but then there is no space for a fan.

I would use a standard triple rad,the stock fan that is in the case to screw it down and then add two normal fans to the rest of it.

Of course you could always mod it with a normal fan..find some spacers or something like that.

Thanks for the info guys, it looks like the XSPC double thick rad will be too think (it think it would hit the motherboard itself!) sadly.
