​Each server is tested for 7 days of up time, as well as all other operating variables including internal temperatures, power drawn from wall, and 100% accepted share hashrate. NO SERVER, leaves my hands without being fully tested to ensure 100% satisfaction. There is no sense in having unsatisfied clients. I take every step needed to ensure any client I work with is satisfied to a Tee. This includes providing you with a 90 day warranty on parts, and life time support for any rig purchased by me. Do not hesitate to contact me through email. I am fully available to answer all of your questions.
