I have pre-ordered two of the 5mh/s Viper units and I am looking to sell those pre-orders for the exact price I paid so far and nothing more, I am not looking to charge a shit load on a pre-order but only what I have paid so far which was 0.81 btc each. If you are interested I can provide proof of my invoice, once I hand over the login details to you, you then can go in and change all the billing and shipping information. If you are a batch 1 customer then you get first calls on batch 2 orders
