I'm with Acill on this one. It's an interesting hobby machine but at the price you are paying you would be expecting a modern day system that can cope with all what that entails and this isn't it. At least not until the OS catches up. And who is to say it will in the lifetime of this machine? For me it appears to be an expensive cul-de-sac.
I think the A1222 may be a more attractive option given it's lower price point and once it actually is released.
This is all my opinion so take it for what it is. I honestly have no use for this machine. I have my classics for retro fun and I have my modern PC for daily stuff so perhaps I am not the target audience for the PPC Machines.
But if you are set on an X5000 then I hope it brings you much enjoyment! To each their own.
