I bought a 500d RGB for my first ground up PC build, and I decided before I began that with such a stunning case cable management will be key, and being a bit OCDish at the best of times I figured I can make something which displays as close to zero cabling as possible.
Inside was easy enough to keep tidy, not a cm more cable exposed anywhere than was absolutely necessary.
The back, on the other hand...
I left it like this for a week or so while I ran the PC to make sure I wasn't going to have to change any components and then decided to get to it.
It seemed a fairly daunting task, but some logical thought and grouping of cables in a step by step manner and a lot of zip ties later it came together quite nicely.
On the whole I am very glad I chose this case, and having selected it ran with the Corsair ecosystem throughout, the CMDR Pro and Hub seems complex but this forum helped enormously, and I've wound up with a PC I'm as happy looking at as working or gaming on.
