Here's what I did with my cable management loooong time ago.
There are a few things I skipped but I think you get the point. I wish I still had it so I could make a video.
I wish I saw this picture earlier today because I struggled with the 8 pin CPU cable. I never even thought about routing it before installing the motherboard. This weekend will be cable management, round 2.
My only gripe with the case is the jet engine I ended up with for a side fan. Even when it's set for only 750RPMs my S-Flex sounds like it's blasting off. Still, I really can't complain because I knew the window made a lot of noise before I bought it.
Have a safe and happy new year everyone. Don't drink too much.
