I had the same. I thought it would be the same width as my PC7+... its not.
You've done a pretty good job as cable tidying in this case isn't easy.
Have a look at BradMax57's thread here to see how he's made it tidier.
I found that using the onboard fan controller is a pain as its located in a really bad place and then you need to use a molex power cable to power it (found a sata>molex converter, but still).
Also 1 think I noticed, you might want to consider turning your PSU around so the fan is over the GPU unless you have cut ventilation holes in the side fo the case.
