I'm looking for a mining server suitable for deployment in Colombia. The device should have at least 1 port to accommodate our network requirements. Please provide me with options that meet these criteria, including specifications, pricing, and availability. Additionally, it would be great to know any recommendations you have for optimizing performance in a mining environment. I'm particularly interested in details like power consumption, cooling solutions, and any warranty or support options available. Looking forward to your response!
