With the HJ rad/pump you're saying to fit it on the top or on the side mount? I imagine it wouldn't fit on the side even with the Noctua 15mm fans?The only one I can think of is the hanjiang pump/rad combo who's is a 240mm 17mm thick rad, and lengthwise it will only barely fit.
Where in line are you thinking of putting it? GPU side would have 25 mm at best, and on the other you've got no space between the rad/fan/PSU or the space between motherboard and rad/fan, and of course you will have to work around the CPU block, RAM and VRM heatsinks.
And for in-line I was just eyeballing this guy's build:
Was wondering if I could just attach two DC-LT 40s together in line where he has the one, but not really sure it'd fit :-/ Or maybe it could squeeze in on the CPU block and have a direct line into/out of CPU block? I did that on my wife's Ghost S1 build.
