Can you install Roon software on it?

Yes, but it doesn't have a premade package like Synology devices do. You'll have to run it via container using Docker, or else virtual machine in VirtualBox. I have yet to mess with it and get it up and running since the a very powerful system is recommended for the huge library I have, and the Asustor just won't cut it (nor would any consumer grade NAS). For a more modest library, it would most likely be fine.

great review thanks for posting. Have you tried running it hardwired via ethernet into a streamer then DAC? Only reason i ask is i initially ran mine (synology 918+) via usb and the improvement via a decent ethernet cable (supra cat8) was instantly noticeable.
