Cics, congratulations, this is an outstanding work. Because people tend to disregard free advice, I'll put a price on it. It can save at least 20 -30 hours of testing and tweaking time to someone starting from the scratch. Depending of person's billing rate, it can save from $400 upwards. (I am playing with PC servers for two years and know from experience what time waster it can be.)There is nothing I would change. I would add:
Under 3.2
PC case - Case is an important part of PC server and has to be chosen with the utmost care. Minitower case provides better air circulation and is preferable to desktop case, but it is an eyesore in audio environment, unless someone has Theta Citadel or Thorens amps :-)
If desktop case is needed to match the rest of audio equipment, it has to be chosen with special care to air circullation:
- choose multi compartment case with walls separating motherboard, Hard drive(s) and Power supply areas.
- choose case with two 120mm exaust fans. Large fans can be set to
operate almost silently when powered by 7V (i.e +12 and +5 instead of +12 and O)- choose a case with bottom and top perforations to allow for convection cooling (like valve amps)
Before installing ANY components into PC case, dampen the case thorougly to prevent ringing from vibrations. Dynamat or EVA kits are the most effective. Make sure not to block any perforations on the case.
-Use sorbothane gaskets under the exaust fans, under power supply, and under all screws, including Hard drive. Consider using Vibrapods instead of provided feet. Also, consider placing 3" thick maple board under the PC case. Because of the applied materials, it is more economical to go with the steel case than Aluminum.
-PC case is sometimes not rigid enough for audiophile use. Brace it with Aluminum square tubing. An audible difference.
3.5. Use good quality AC power cord to your PC. At least 14ga, with quality plugs.
