I am trying to spec out a workstation PC that is to be stored in a air tight container. Also the computer might receive some rough treatment. Basically this workstation will face a rather extreme environment.
The specs don't have to be stellar, however the computer would require quite a few expansion slots (PCI & PCI-X).
I'm having trouble specing something out.
For the CPU I was thinking either and undervolted e5300 or Amd Business class series cpu. Or maybe a mobile CPU would be better?
How big is this airtight container? You still need to remove heat from within then container. And if it's going to experience "rough treatment", you should get a low profile, lightweight cooler (like the stock one) to minimize stress on the motherboard. Your problem isn't going to be cooling the cpu. The problem is going to be removing that heat from the closed environment.
Getting heat out will not be that much of a problem. The container will be pressurised with air moving out of the container. However electrical interference (think motors starting and stopping) and vibration are an issue.
The computer will go in an explosion prroof enclosure and is to be used close to some rather heavy duty machinery.
