@KSliger Is the handle attached to the frame with a mechanism that would remove the 280 mm rad option in the sm580, like the cerberus, only leaving a 120mm fan option?
The SM570/580 both have a radiator/fan/HDD mount bracket that is included by default. This bracket has the standoffs for the handle - in turn the handle kit is just the handle and screws, and the base chassis without the handle does not have any less cooling functionality.
I understand, I will say personally I don't care about window panel's I never build my systems for display just for functionality and as compact as I can. Given the option especially if it is cheaper I will always pick vented side panels for both sides. Possibly even solid panel for the CPU side if testing proves that to be more effective.
I think personally the best setup for cooling will be solid panel on the CPU side with a 280 mm rad on top exhausting and two 140mm fans on the bottom exhusting with a vented side panel on the GPU side pulling in air.
My only concern with this setup is the RAM and VRAM not having enough air flow to remain cool, which may ruin the idea of a solid panel on the CPU side.
I can see this being a decent setup, RAM and VRMs should be fine as there will be air moving over them, just not as much as if the fans were all facing to blow out top. Will give it a test!
