Very clean build, I have personally ordered PSlate Customs unsleeved cables for the Meshlicious, since those are thinner and much more flexible than traditional braided ones, such as yours. They can be easily routed behind the motherboard, which makes for a very clean build overall.
Interesting to see that you have put the AIO fans on the inside and as exhaust, rather than on the outside. Kinda looses their RGB function as they aren't that visible from the front.
I'm also going for that PSU orientation, with the TG panel. How do you think it will do? Being so close to the panel itself. I'm aware that you can flip the PSU bracket and hence have the PSU slightly floating and getting a bit room between it and the panel itself.
