How to do it...

Now it's time to do some more research. Follow these steps:

  1. For our ideal count of active (not replacement) hard drives, remove any choice that doesn't have enough drive slots. Use this list if it's not immediately obvious:
    • Maximum 2.5" drives in a 2U server is 24
    • Maximum 3.5" drives in a 2U server is 8
    • Maximum 2.5" drives in a 1U server is 8
    • Maximum 3.5" drives in a 1U server is 4
  2. Refer to the final list of servers from our motherboard selection.
  3. Remove from consideration any chassis that does not support dual power supplies. This should rarely happen in server-class systems.
  4. As the list dwindles, give higher priority to cases with more fans or lower average operating temperatures.
