I addressed similar requirements with 3 dedicated devices
1: Main PC - quiet Antec P182 Main build, wake on lan in another room.
It does't have to be silent, as its not the main listening room (lounge), and when I'm in the same room its headphones, or i'm listening/watching so I don't tend to notice the background noise. Wake on Lan means its only on when it needs to be
2: a re-purposed Dell mini 9 with SSD and external USB Hard drive. On 24/7 , but at only 5-15W vs 200W draw of the main PC. Can administer remotely to task it . Shuffle stuff off it when ratio is reached. Network shares So I can access stuff as soon as it is complete. Sits by the router.
3: Dedicated video playback device HDX-1000 (with added 2.5 inch internal laptop drive) . Fanless , 1080p HDMI output , networked (wired) to the main PC where addition storage is available by the myiHome server software or shares. Can't recall the last time I played a shiny silver disk, as its all ripped, then the ISO image played back over the network.
The HDX software lacks polish compared to other solutions, but plays what I want, and is controllable via a remote. which is what you want.
Thats just my approach and it works for me.
