Question Z390 Designare graphics card sizing

[fall3n]

A few months ago I built a PC with a GA Z390 Designare motherboard. Everything works but I remember that due to the components on the motherboard, the graphics card did not fit in the slots so I had to buy a PCi extender, plug that into the motherboard on one side and the GPU on the other and then just rest the gpu on the floor of the case.

Is this a compatibility issue with the Z390? I also bought a midtower case, so I was not sure if the case size had anything to do with the gpu issue.

I ask because when I am gaming, there is a lot of heat coming from inside the case which is probably due to the gpu just sitting on the floor of the case.

there shouldnt be any compatibility issues between mobo and gpu

its not a chip incompatibility or anything, the actual physical graphics card does not fit in the case when plugged directly into the motherboard and I don't know what to do about this weird problem except buy a new graphics card... I do not want to spend that money, so is there another, cheaper solution like buying a new case?
