Been doing some research lately on what it takes to build a truly silent motionless PC for audio playback. For now this is just a collection of thoughts.
Requirements:
- 100% Silent
- Low TPD CPU
- Off-board USB
- Pico PSU so that transformer is away from case
- SSD for operating system
- JRMC 19
- Min 8gb memory
Notes:
- JRMC can run in 64 bit mode so Win7/64 or greater OS.
- 8gb is more than enough memory for JRMC 19
- JRMC cannot use virtual cores so a Quad-core i5 is the max processor
- The lower the TPD the less chance of heat and distortion
- A SATA 3.0 cable is a must as it separates cables within cable
- Samsung 840PRO seems to be the fastest SSD available
- The Paul Peng $300 USB card (Link) uses the NEC uPD720202 chip. A similar board is avail thru Newegg for $20. It appears as though you could build a Molex to battery pack to power it separately.(Link)
- Any necessary connectors are avail from FrozenCPU.com (Link)
- Portatech is a good resource for checking prices and relative processor speed.
- The quad-core haswell processors can run as low as 65w with all four cores running (Link)
- L3 cache is the most important memory for real time audio playback.
- Investigate using something like ERS cloth (Link) to absorb EMI inside the case. Considering this is basically metal tape then I wonder if something like aluminum foil tape or furnace tape could do a similar job. The only way to know for certain is with an EMI meter.
