t1 slotGreat build. My Asus RTX 4070 was 2.56 slot which is 2.75 for T1 and I wanted EK AIO too, but sadly won’t fit. I love this case and the build in general with i5-13600kf. One of the beautifulest cases I had in my life. EnjoyTry 2.5 slot and if you get a lot of turbulent noise coming from the GPU fans being too close to the side panel, move to 2.75 slot.
