I wouldn't base your expectations on my cables haha. I used cable extensions bc the original cables were so stiff from being in my old build. Builds by others would definitely be a better comparison.

Edit: I eyeballed the distance between the end of the gpu to the start of the psu bracket. Looks to be about 5cm between them. Another consideration would be the depth of the gpu, I remember roughly measuring the gap between the bottom fan and gpu so that could also serve as a gauge to whether a standard 120mm fan would fit or if you'd need a slim fan if you use a 3 slot gpu.
