Their ARM boards are supported by Armbian and DietPI, the X86 ones should run anything that works on that architecture.

I have an old Odroid-XU3. Last week I installed Ubuntu 22.04 on it. The OS image for Ubuntu 22.04 that I am using is the one officially provided by the makers of Odroid.

I wrote a document with a few notes about the Odroid-XU3.

Their x86 boards can run whatever, they have mainline Linux support.

They've also been maintaining Linux support for their 8+ year old ARM boards, as well. I generally avoid ARM boards because you're dependent on manufacturers for continued kernel development, but Odroid/HardKernel/whatever holds up their end of that deal very well in comparison to other manufacturers.
