Is there any reliable way to install High Sierra on an older PC?

I'm asking because I'd like to play around with an old Mac setup again. I still have my old boxed copy of iLife, and I'd love to go back to GarageBand.

I have an old PC with a Z390 motherboard and an NVIDIA GTX 1070. I was thinking about installing High Sierra because I don't want to spend money on a nostalgia box. I also have no interest in running newer versions of macOS, especially since they no longer support many older applications. Ideally, I'd run Leopard or Snow Leopard, but I don't have compatible hardware, and as I said, I don't want to spend money just for nostalgia.

The Dortania guide has been a complete disaster for me. I managed to put together a reasonably decent OpenCore configuration by following it, but the installation always fails. Then I found out elsewhere that the Recovery images downloaded under Windows are basically useless—they simply don't work.

So I installed Catalina in VMware and downloaded the full High Sierra installer from within macOS instead. Same story again: most of the servers and download commands for older installers no longer work, and when I finally managed to download the installer, the createinstallmedia command that was supposed to prepare the USB drive crashed after running for a while and eventually returned an error.

Is there still a reliable way to create a bootable installer for an older version of macOS and install it on older PC hardware?
