Well, they do sell the only modern CPU that doesn't come with baked in backdoors, so that's something. Power servers from various OEMs are relatively new (e.g. Raptor, Tyan, Wistron, etc.) and are really pushing the open systems / open firmware angle. These are the same line of CPUs in Sierra and Summit.
Or you can keep buying buggy Intel/AMD systems with mandatory backdoored firmware required via hardware signature checks. Just remember, they have no responsibility when your data flies out the window, see EULA...
I would definitely stay away from Lenovo or even IBM badged servers though -- they're all Chinese rebrands without the open firmware advantages and shoddy hardware half the time.
