The Inwin D 2.0 is an open frame design. Just a bunch of tubes. It comes with a adapter plate with 3x 120mm fan holes and 2x adapter plates with 1x 120mm hole.
The radiator attaches to that adapter plate, 3 fans go under the radiator and 3 fans go on top, the radiator ends up looking like a hotdog in a bun. The adapter plate mounts to the framework.
You are allowed a total of 90mm thickness for the front mount position, any more than that and you interfere with the motherboard.
Each fan is 25mm thick, the radiator is 27mm thick. Total 77mm hotdog bun. So you have a little room to spare in push/pull but not much.
According to Inwin, the 3 fan position on the bottom is only allowed 65mm. So your hotdog bun would be too thick and interfere with the bottom of the motherboard.
Inwin says push/pull front mount only.
