Could you doublecheck my first build?

After days of research, I've decided to go for it and build my first Hackintosh! Could you check my build and help me with my last choices?

• Motherboard: Gigabyte Z370 Aorus Gaming 3 (gonna upgrade bios with a borrowed 8th gen chip)
• CPU: Intel Core i7-9700K
• Memory: Corsair Vengeance LPX 32GB DDR 4 3200Mhz (2x16GB)
• Power: Corsair RM650 80+ Gold
• Storage: Samsung 970 Evo 1 TB M.2 NVME SSD
• CPU Cooler: Still in doubt: Corsair H100i PRO or Noctua NH-D15
• Graphics: Still in doubt: Sapphire Nitro+ Radeon RX 580 8GD5 (€ 200, fast enough for graphic work/light 3d work) or MSI Radeon RX Vega 64 Air Boost 8G (€ 275, seems like a good price)

Last time I built my own PC was 12 years ago, and it's fun to be digging into hardware again. Also gets me quite some nerd credits from my boyfriend :-)
