I think you've got the AIO pump plugged in the CHA_FAN1 header, rather than AIO_PUMP which is just next to it?
You've fit the radiator the other way round to what I explained though
I think if you try to put the GPU in, the pipes will be in the way... You might get away with it, but I'd flip it around.
Ideally you should flip the radiator so the pipes are coming from the top of the case, so it's not near the GPU. I'd also flip the AIO on the CPU itself, so the pipework on that is orientated to the top too. It should mean you can route the AIO_PUMP connector cable neater, as you can tuck it around the edge of the pump and then plug it into the AIO_PUMP header. If that makes sense?
The white fan connector cables you've got dangling, you can route them just at the top of the case behind the motherboard, then bring them back out near the headers you connect them too, if you wanna make them look tidier also.
For the case switch cables (power sw, reset etc) do you know where they go now from my last post? I'd route those also behind the motherboard tray at the top, then bring them up through the bottom hole of the case - so they're on the bottom right of the mobo so you can connect those up neatly as well.
Edit: Just to take a little bit of inspiration from (cable routing wise), I've added a photo of my PC just to give you an idea how best to route your cables to keep things relatively neat. So you can also see my case connectors route round back and come out to the bottom right to my motherboard, and my AIO radiator pipes are at the top instead of bottom? You want it something like that.
Edit2: Lol just saw the imgur album name. You love the bane of building PCs, it's good fun
