It would even allow the use of the SX500-LG SFX-L PSU without issue due to it's short PCB, because the heatsink sits lower. Also, the effect of having the bottom fans right up towards the heatsink would allow optimal airflow through the heatsink. I like this setup (GTX 970 + Arctic Cooling Twin Turbo III + two 25mm case fans) because it will perform quietly but also efficiently dissipate heat.
My thoughts as well. This one is maybe better suited than the accelero extreme (that Necere tested). However, I wonder if the backplate fits without issue, because VRMs might need some cooling...
That's why I am interested in what GTX 970 it is, if it was reference design and if they all have the same placement of the core on the pcbs.
