You have two inserts with this case. 3x120 or 2x420mm. The warm exhaust air is released via the side panel. I have a current I7 13700kf with an AIO and Diablo 4 that settles at around 46-58 degrees. The case is top and very spacious. The cabling is very well solved and I would buy it again.

Which one do you mean? It has two glass plates:
the inner one with the fan bracket (you get one for 240mm and 360mm) or the outer wall glass above it?
You can leave out the glass plate with the fan bracket if you don't want a fan there ;-)
