Cube cases for ATX Mobo?

[sniip]

Hey guys, i'd like some suggestions. Should I change my case and what case I should buy? I have a mobo ATX form factor, my current case is some Zalman case (don't know exact model), also I have RX480 Gaming X gpu and a BeQuiet Pure Rock CPU cooler. The problem with current case is that it's under the table and it's very poorly ventilated and my GPU gets quite toasty (around 83C while gaming). If I open the side door the GPU  temps drop to around 70C under load but it gets louder and dust collects very quickly. My idea would be to take the PC on a desk but the problem with it that it has very little space (225mm height 400mm lenght 400mm width). My current case has one intake 120mm fan and one 120mm exhaust fan at the back and there is no more possibilities to put any others.

 

Maybe someone can suggest some solutions? What case I should get or how I can make my current setup cooler?

 

As I seen the "cube" solution probably won't work since of the height limiting factor. I think sticking with a mid tower would suit better. Maybe you guys can suggest what case I should get? I was thinking about BeQuiet Pure Base 600 but some people tell me it's not worth it. Also how many and what kind of fans I should get with the case? (Silence for the build is priority)

Any corsair air case is pretty good

This would work perfectly but the problem would be the height of it... At max i could probably only fit 350mm height cases
