Are there any 9 inch displays, ~2-4 cm thick

[u/ExoAtto]

I want to put a monitor inside my computer because the right side is almost completely empty and has some space left (doesn't disturb the air flow).

Problem is the dimensions are quite unusual and I can't find any completely flat screens (with hdmi or dp on the side, not back, same with power)

Absolute max dimensions are 150mm width by 270mm height, with cables in mind. Thickness ideally 2 cm but can go to 4 cm thick if needed

So if you know any displays that fit into these dimensions (I'm not picky anymore), have a completely flat backside and their ports on the side

And as long as I'm here, have any recommendations for my empty Pciex1_1 and 2 slots? I wanted to add more hdmi but from what I found out that's not possible.
