Roon core on Synology DS 918 + with 8 GB RAM, 2x256 GB SSD cache holding appx. 30.000 titles an +3000 albums. Playing to Raspi 3/4 devices running ropieee connected to everything that can make music audible (Hifiberry, SMSL SU8 Dac via USB and 1 directly into Edifier S3000pro active speakers). Still waiting for a really sufficient streaming device. Listening equipment and speakers change often, so this is “fun in progress”.
