Pegboard PC
(lemmy.world)
I designed 3D printed components to mount my ITX + 3080 + SFX to an IKEA Skadis pegboard, so it can be wall-mounted behind my TV.

Might not be that bad. My computer picks up way less dust sitting on my desk surface than it did when I had it on the floor, and I imagine OP's TV is mounted at least as high as that.
