Just sharing my experience in cable management with the case that's good for that purpose.
Cooler Master H500M is the case that I have been wanted since it was revealed; mainly because it's not a boxxy design like many other case. Once I got this fresh on my hand, I instantly love it. So many things that I can do inside this case.
The side panel for managing cable has lots of space compare to my previous Thermaltake case. Those cover panels are definitely great to hide all cables since the side panel is tempered glass.
I don't use many tie down points there and not much of zip ties or cable ties to permanently secure the cables because I plan to swap the components very soon.
So, all of these are just temporary. That RGB fans and controller are pretty much swapped later because the controller uses molex, which is a pain and I will go for CM Halo fans with its built in SATA powered controller.
Excuse my laptop HDDs there because all my important datas are still inside after my laptop is faulty and even my 8TB worth of space HDDs already full. Also, good thing that this
case has GPU holder to un-sag the heavy GPU, which is also planned to be swapped with new RTX.
I also realized after looking at the front side that maybe I should route the ATX cable behind those steel panel instead of through rubber grommet/cutout since it's not in the optimal place.
