Can you provide me examples of the mining containers you are referring to so that I can understand what you are comparing to?  Cause cheaper ones we have looked at have problems things such as insufficient airflow or sensors to regulate fan speeds, don't have electrical systems up to code, don't have redundant electrical safety, etc

So what companies are you talking about that are making these amazing inexpensive miners?  im sure they would love the free promotion.
