Couple of things:
-
You have a bunch of pcie 5x4 SSDs but you only have one pcie 5x4 slot. You should replace most of them with pcie 4x4 and bear in mind you may not have space for huge heat sinks on each
-
the case has a top mount spot only for the 360mm radiator you chose. You need to buy some exhaust fans (120mm or 140mm) for general airflow.
-
the problem with bigger and better PSUs is that… Well, they’re bigger. Double check the dimensions of the PSU will fit the slot your case has allotted before you splurge on it. I highly doubt you’d need 1kW with that spec so consider dropping the overall wattage a bit as needed.
-
Your gpu is water-cooled it seems like. Make sure you have space for the second radiator, because you’ve already occupied the only 360mm slot.
It looks like the radiator support for 360mm is limited to the top side. I also think the case was designed around vertical air cooled gpus or a custom cooling loop for the whole assembly. However I would honestly recommend against a water cooled gpu in this case. You’ve already got an AIO with the CPU, and an air cooled gpu in this set up will have no problem with airflow.
As for power, just get what you need and add like a 15/20% buffer minimum for the misc things like rgb or small fans. The rated TDP of all devices is available in their spec sheet.
