That would be without disks
I've got enough disks already. Even so, it's cheaper to source the required size/disks yourself.
Of course M have only said that Core could be run on a QNAP (for which I thank them). What they haven't said is what spec QNAP is needed to run Core effectively.
Given the spec for Roon to run effectively it remains to be seen how much M can squeeze out of a relatively lower specced NAS CPU and RAM.
Last week, I discussed the merit of running the MDMS Core on a QNAP TS-251 with Des Ford at M. He didn't contradict my premise of running an MS200 from a TS-251 with MDMS Core.
You can add extra RAM to a TS-251/451 yourself. It sports a 2.41GHz dual-core Intel processor, so I wouldn't exactly call it underpowered.
