Guides to golden build with a Z390 mb and a Sapphire Radeon Nitro+ RX 580 8GB

I've been lurking here for quite a while now b'coz… well… I'm broke and couldn't afford to build a good PC to Hackintosh. Now I'm finally ready to take the plunge, and I have some questions. First, I was thinking if it's easiest to search for a cheap Dell Inspiron desktop (heard they're easiest to Hackintosh) and just swap out the graphics card to this Sapphire Radeon Nitro+ RX 580. I wonder though if the power supply can handle the load.

Next option is to build it from the ground up. I've read good things about the ASRock Motherboard (Z390M-ITX/AC) having onboard Thunderbolt 3, (although I'm not sure if it'll work). I'm looking for any tutorial or guides to follow and build it.

Help much appreciated. Thanks!
