In 2014, my uncle gave me his old #PowerMac #G5 as he bought a new #Mac for pro video work. There was some kind of hardware issue with it, IIRC.
I had one helluva time getting #Debian installed on it. It kept failing to install the boot loader, which wasn't #GRUB. Anyway, I figured I would install #FreeBSD. It installed fine, booted fine, performance was fine, NIC supported, but....
It was a Tier 2 architecture. At that time FreeBSD, while supporting multiple ISAs, prioritized them in terms of support with x86-64 being Tier 1. Tier 2 doesn't have nearly the same level of support from the FreeBSD team.
In my case with the G5 only ports, not packages, were available. EVERYTHING had to be compiled and installed. Aside from some shells and other CLI tools, builds took ages and often failed.
Here's more info about the tiers.
