Fanless Computer with PCI-E Expansion


Recommended Posts

hello sandston - i've got a project in the works to do the same. After giving up streaming via NAS due to noise and dropped signals, here's what some research came up with:

 

Design Criteria

 



    1. It's tiny
    2. It lives by the Stereo (connects to a DAC and Integrated Amp)
    3. It holds all music, in all formats (m4a, mp3, flac, wav, ogg, etc)
    4. It plays 24bit/192kHz without any downsampling - HD Audio Codec (Realtek ALC269 or better)
    5. It syncs wirelessly with other machines (i.e. for running back-ups, managing additions, editing the library), preferably via WiFi rather than bluetooth. (802.11 b/g/n)
    6. DNLA compliant
    7. The operation is controlled via remote, from another machine, Android phone, etc. (PC, Mac or other) - WiFi (Bluetooth could be offered as an option)
    8. It uses an already existing free music app for management, play, remote control, etc - e.g. musicbee, foobar2000, vlc, etc so users can keep using what they like. Nothing bespoke.
    9. It offers 2+1 USB (two 3.1 type A and one type C) for connection to an external DVD/CD burner and whatever other device (USB key, external drive, phone, iPod, etc)
    10. TosLink S/PDIF for connecting to a DAC (or DAC/Amp). Option for mini-TosLink/3.5 audio jack out.
    11. Coaxial option for connection to a DAC (or DAC/Amp).
    12. Low or no noise components, so SSD drives. Passive cooling.
    13. Has capacity for 1Tb memory. These should be easy to swap out, so accessible
    14. Includes LAN port for hardwired net connectivity - Network RJ-45 10/100/1000 Mbps ethernet
    15. Low power (it'll be on all the time), at or below 25W
    16. Video port is an option, but not critical. HDMI?

    As yet, there's no plug-in like the HiFiBerry, but that couldn't be far behind.

Hope that's not too much... The last few options would require some work to set up, but could be made quite lean if all they're doing is sending music to a DAC.
