"Major plus is that it fits my RTX4090(Windforce2 three slot GPU from Gigabyte). Only minus is the case is noisier if your components are not sound optimized as the mesh panels do not block any noise. ...A great “ITX” case....Only reson I’m giving it a 4 out of 5 is that it’s the largest ITX case i have built in and this would be my third ITX case but this is now my main case and I personally love it."
