You could put Linux on it and use it as a sort of jukebox, or any multitude of other things. You could also send it to me if you aren't interested in doing any of that :)
I use Linux on mine. It's a bummer that the magic to send over 2 eDP tiled at 5k resolution was never open-sourced, so you can only send 4k and it ends up slightly blurry.
I'd love to put Linux on it, but one of the main reasons I use Linux is for CUDA programming and you can't even put an nVidia card in a Mac these days.
