My idea is (and I am not sure if it is doable yet) to take out the mainboard (powerpc based) and replace it with an Intel maker board (maybe this one)
I found a picture online of the inside of the device:
What I am currently trying to figure out is, if the display and the control buttons can be utilized with a different board. If this works it would be a nice combo for a Roon Server as it looks very well like a hifi-component.
If you have plans or ideas regarding this or your own servers. I am interested to read about them.
