Just noticed that on the WebHostingTalk forum the price is only $50/month and here it is $150/month. I know I'm missing something.
It's a matter of power usage and from the lack of info on the WebHostingTalk forum. There the power isn't mentioned and typical 1U servers need just around 300W-400W to run. Quotes from DataCenters include only a limited amount of power per U space. Bitcoin miners are unusual when it comes to this because they need A LOT of power compared to regular servers.
