Music Servers with JRiver are Baetis Audio or digibit (To my knowledge they have adapted JRiver to their needs) for example:
http://www.baetisaudio.com/Prodigy.phphttp://english.digibit.es/index.php/aria.htmlBaetis has an interesting presentation on their website about their experience what is for example the best audio interface.
If you have a big collection of music, video a NAS is a good solution to store your files. (also recommended by Baetis)
I have build my self a music server with a 12 TB QNAP NAS:
1 x Fractal Design Node 605
1 x Seasonic Platinum Series Fanless 400 PSU
1 x MSI Z87M Gaming Mainboard; Killer LAN
1 x Intel® Core™ i7-4770T Processor up to 3.7 GHz, 45 W TDP 8MB Cache, 4C/8T
1 x 8GB (2 x 4GB) Corsair Vengeance DDR3 DRAM 1600MHz C9 Memory Kit (CML8GX3M2A1600C9)
1 x Noctua NH-UB9 SE2 (CPU Cooler) + 1 x Noctua NF-A9 PWM (replaces packaged fans)
2 x Noctua NF-S12A (Case FAN)
1 x Intel Desktop LAN (Dedicated Ethernet Interface to Devialet D-200)
1 x EVGA GTX 960 SSC 4GB GDDR5
1 x 500 GB Samsung 840 EVO SSD Three-layer Cell Solid State Drive
1 x Samsung SN-506BB/BEBF Blu-Ray drive
1 x SOtM tX-USBexp Audiophile PCIe to USB Audio Card
I use it also for gaming and playing video with madVR. From 3 meters distance you don't hear any noise. From a sound quality perspective the dedicated Ethernet interface to Devialet D-200 sound best. USB 2nd with optical, Win 10 and new Realtek drivers very similar. Because you have a McIntosh USB or SPDIF (RCA/Optical) are the connections of choice.
On Computeraudiophile you also find some fanless builds under

I would use only local storage if your collections fits to a ssd.
