I don't know how you think you would have received any miner ordered on Wednesday by today on this planet....not to stick up for bitmain but you order on the 26th so IF it shipped in 48 hours and made it to the Friday cutoff (big IF)....you would have a chance to get it by this Wednesday at the earliest depending what part of the world you are in...but back to your unrealistic expectations and reality....your miner will most likely ship today and you should have it by Thursday depending where you live and customs etc.... as for cancelling or modifying your order....its not possible from my past experiences with the company as its already been processed so wait and enjoy your C1 kit its not just cool...its COOOOL
I will say its a lot quieter and easier to manage than 2 x S3 once you get it running
