First of all: You need a case. Something like the NZXT H510 is a great starter case and will fit all this hardware.
Processor: Pretty good. If you want you could go 10th gen and get a Z490 mobo too if you want.
Motherboard: Also pretty good. I would recommend Gigabyte and Asus for a Hackintosh, and you made a good selection.
Graphics Card: I wouldn't really recommend XFX for graphics cards, I would highly recommend trying to get a better brand like Sapphire. The RX 570 is a pretty good overall card for 1080p gaming.
Memory: I would recommend getting something faster, like 3000+ rather than 2133. I would also recommend getting something a bit higher end, like Corsair Vengeance LPX or G.Skill Ripjaws V. If you want more of a budget one, G.Skill Aegis is a good choice.
Storage: The 960 EVO is a good choice, but kind of old. I would recommend getting something newer and faster like the Western Digital Black SN750.
Power Supply: Totally overkill. It's fine that you have a high wattage, it's just that your system could easily run off of a 550W unit. I would try to get Seasonic as my no. 1 brand and EVGA as no. 2, but Corsair is also pretty good. FYI I also use a RM850x, and I have had a few problems with it here and there, so I'd recommend you get something like a Seasonic FOCUS GX-650 or EVGA SuperNOVA 650 G5.
AIO: Good. If you want something a bit better quality, I would go for the NZXT Kraken M22 if you want 120mm you could also consider something like the H100i from Corsair if you want something bigger.
