I have been playing with Linux for awhile, and determined that an older desktop that originally had Windows 2000 Pro is too outdated, and will never work fast enough to be usable.

I have spent some time researching new hardware, and am looking at the mentioned motherboard for the heart of a new computer, which will use an AMD CPU, 5 3600X.

Are these good selections? A telephone inquiry to the Asus help line said that this motherboard might be used, but that Asus provides no support for Linux OS's.

Is there a listing of mobo brands/models, etc. for making decisions about this type of question? Are there brands of hardware that are best for running Linux? I don't want to spend money for motherboards, CPU, and RAM, which will not be suitable.

Thanks to all of you!
Best regards,
OLD Jim

You'll really need to run a 5.0+ kernel, but as long as you do have a modern enough kernel, yes, the 3000 series is well supported by linux. Not familiar with the board to say if there's any onboard hardware that WON'T work, but it's becoming uncommon to see hardware that doesn't work with linux anymore with the exception of wifi (and even that is far less often than it used to be).

Any distro that uses an unpatched version of Systemd release 240 as the init system will not boot a Ryzen 3000 cpu. That's Ubuntu 19.04 (and derivatives) and Arch and Manjaro (unless they've fixed their installation images in the last couple of days). Fedora 30.

Ubuntu 18.04 uses systemd 237 and works great. Once 18.04 is installed you can now upgrade directly from 18.04 to 19.04 and that will work because the repository version of systemd has been patched, but the patch has not been applied to the installation .iso.

Debian 10 uses systemd release 241 and works.

Any distro that doesn't use systemd at all will probably work, especially with a 5 series kernel.

I'm using Ubuntu 19.04 (via an upgrade from 18.04) on an ASUS ROG CrossHair VIII motherboard with a 3700x CPU. No problems, but I don't overclock or play benchmark. The kernel sensors that allow monitoring temps/volts/freqs hasn't been updated for Zen 2, but until that happens you can kinda keep track of what going on by listening for the fans to ramp up. I can get xplane to do it, but nothing else I've tried moves the fans off idle.

The fanbois are complaining that BIOS problems across several vendor's x570 motherboards inhibit overclocking fun, so while I don't have any operational problems, this machine won't become my main production desktop until there have been a couple of BIOS/AGESA updates issued and stability further cemented.
