For a while now I’ve wondered how to build the most stable gaming/workstation possible. I’m sick of crashes, stutters, and general un-reliability. However, it’s a balancing act between price, performance, and reliability. (for example ECC memory is stable, but more expensive and slower)

Ideas I’ve had:

  • ECC memory
  • CSM sku motherboard
  • Hugely overkill power supply, or even dual redundant PSUs
  • RAID M.2 boot drives
  • All air cooled

What do you all think? If you were to spec out a (realistic) ultra-reliable PC what parts would you use and why?

P.S. I’m looking less for specific recommendations as I am for general ideas, which is why I didn’t specify the use case or budget. I’m more interested in the concept and if it’s feasible.

    • Warning! Mil spec hardware by definition is literally the lowest bidder on a government job. Just because something says milspec doesn't mean it's the best. Usually it means it's pretty mid tier. I have had some good experiences with milspec gear, some OK experience, and more terrible experiences than the other two categories combined.
