Pentad,
You do realize MorphOS isn't supported on Amiga PowerUP cards anymore right? All you have is the legacy 1.4 release which as Magnetic said, is free.
In broader perspective, even if Amiga derivatives ran on commodity hardware you'd have the same issue faced by GNU/Linux and BSD on a larger scale: Lack of drivers due to developers being limited to small sets of motherboards and combination setups. And because the majority of Amiga users cannot code at all, you're going to have the same people bitching and moaning about their hardware being unsupported, and since x86 hardware is pretty much junk ( I've had 3 out of the 7 machines I have owned in the last 2 years die or in some cases catch fire ) in terms of build quality any attempt to make "Amigas" via custom built boxes that are 100% supported will be cost ineffective.
I had a colleague of mine in college who has a Pegasos II which has been running 24/7 for nearly 10 years with no failures as a server. He has gone through 4 desktops in the same period and cost himself nearly 3 times the amount the Pegasos II G4 cost from initial investment. He now is building a refurb POWER 5 server and adding a video card to make a workstation. Too costly for me personally, but I think he will get his money's worth before it dies.
The developers of Arix are solving the driver limitations by using one of your hated linux kernels. And I have to say that I know a lot of people owning X86, using it on desktop and/or server with none catching fire so calling it "junk" is nonsense. You have a huge market with lots of different components you can choice from so if you need something 24/7 you use different components. And I have one customer where a normal "junk" PC run since 2006 24/7 without any failure or "catching fire".
