It seems fine for me. My rig isn’t much better, and I think mostly the extensions are to blame. If you want something cleaner, either ditch them or use custom cables. But these are so expensive I really decided I’m fine with how my system is now.
Honestly, yours looks functional and tide, I would just be happy with it.
Since you have a modular PSU, you could order custom cables from CableMod, but they are pricey. Honestly I have the same problem and I’m going to order a new PSU and custom cables from CableMod.
My build so far.
You’ve done a really good job, already. Heck of a lot better than mine.
I said to heck with it once I realized just how much of a pain the RGB was going be. And it’s behind a solid panel anyways; so out of sight, out of mind. 
Oh god, I am glad I am not alone with this problem. xD
wow that’s actually pretty good from the back, and yeah you’re right about that, to get the best cable management is to get a custom cable but yeah I don’t have time for such expensive cables (Saying this to myself as I buy fucking pricey cables for IEMs. Hypocritical of me xD.)
Also I bought a new fan for my Deepcool Assassin 3, since it’s 140mm fan does not let me close the glass panel. USB 3.0 for the pins are a pain in the ass to plug on the motherboard also the sleeves could have been managed well but this is how I can do it the right way.
That gpu support looks intresting 
Yeah I think it’s more of an adjustable headphone stand. Well to be honest I am not so sure what I ordered I just looked up Anti-GPU sag stand and got this. Hey at least it works lol.
@K4sh1ma cables look fine. I’d ditch that top fan that is toward the front of the case. those tend to mess with airflow for your cpu cooler and negatively affect temps.
Basically I don’t need the top fans anymore? I mean temps wise, there are no issues with it so far and the temps are low enough for it to be safe at idle use. I will give it a try and run some tests to see on what you are saying can improve it, though it would ruin the looks a bit, not like it has any aesthetics in the first place anyway.
Just the front one. That’s the one that pulls air out of the case before it reaches the cooler. Or you could just pull the 3-pin/4-pin from the fan hub so it doesn’t spin and you’d still get the RGB and the aesthetic without having to worry about it pulling air from the cooler.
Edit: I think that would work. I’m not actually sure after having thought about it for a minute. That’s not something that people regularly do, as far as I’m aware. But it should work.
I’ll keep that in mind, thanks for the tip. Will run some tests of it when I feel like opening my PC again.
Also I don’t think I will be sticking with the single lighting look for my build for a long time, in fact I am having a plan of me making adjustments of replacing the case fans with non-lighting ones but performance-wise superior.
Honestly that is what the basement is kinda there for as a “cable dungeon” to store all the extra mess. Your already using a proper fan hub to help with the awful mess fan cables can be. Honestly there is not much else you could do.
About the only thing I would do differently is use a comb for the MB and GPU power cables on the front to give them a bit more of a tidy appearance, but the back looks nice.
I’ve never really seen the point in cable management behind the motherboard, except for SATA cables maybe, but I’m more likely to replace an SSD with larger capacity than add another one. As long as you’ve got unrestricted airflow in the front, it really doesn’t matter. You’re not going to keep the unused cables in the PSU box, gathering dust, are you?
All the time. Though to be fair after testing all the components I order custom cables after measuring the length needed to make things easier and I only plug in what is needed.
EVGA finally released the X570 Dark board

AND THEY PUT THE DRIVERS AND MANUAL ON A FLASH DRIVE!!!
Why isn’t this normal yet? ASUS has done this sporadically with some of their highest end boards for, I think 3 years now. They aren’t that expensive, and if you are already being charged $300+ for a motherboard, they don’t have any room to argue about the added cost. Then again, we are just now starting to see fixed IO shields starting to become standard on boards above a certain price point. So who knows how long it will take for them to ditch CD’s in favor of flash drives.
To be fair a lot of the time it just means you get an extra flash drive to use since a lot of times the drivers are out of date if you don’t buy the board relatively early on in it’s life cycle. The IO shield thing is highly annoying though.
