MarcusDutt :
Sorry forgot to add the case model before i rewrote it and its the Lian Li PC08
There's only one Lian Li case on the EK compatibility list and it's not yours... that says:
We don’t have any confirmed compatibility of the selected EK-XLC Predator in this case model.
Have you looked here ?

Space of Radiator:
Top: 120 x 240x 54 mm
Front: 120 x 360 x 70 mm
From previous post, we know that the EK 240 is 68mm thick w/ 1 set of fans
EX Predator with Push = 68mm ... this is too thick for top mounting (68 > 54mm)
EX Predator with Push / Pull = 68 + 25 = 93mm ... this is too thick for front mounting (93 > 70mm)
NOTE: These Lian Li guys could mean however that they have 70mm of room
behind the existing fans... you will have to call and check. If this is the case it should fit in that instance. Take the existing case fans out and the 70mm EK Predator with fans may fit. Be nice if Lian li provided diagrams or better description. Also the EK 360 is a few mm longer than 360mm to allow for reservoir ends....but as almost every rad will have these two, it's a kinda dumb design to put 3 fans in front and not provide room for a typical 360 rad.
They also say 120mm for width ... again mos rads are 123 - 126mm ... if it's really 120mm / 240mm and 360mm dimension allowances in the case, I think they really blew it with this design
Of all the popular case manufacturers, I have found Phanteks to be the most accommodating radiator wise. The Enthoo Luxe has 65mm to Motherboard but it's offset so a 120mm wide rad should do fine inside. Take the pre-mounted fans and out them in the case's "attic", then buy new fans for underneath ... the 3mm shouldn't pose an issue unless your MoBo has something very tall within 3mm of the edge. Of course, you could buy fans slimmer than 25mm but i don't see them being needed for most MoBos
