Hey Everyone, this may sound dumb but what stops a person from just cloning the high end mining machine and just hunt down the individual parts that make up, say the antminer s9? could you build something of that caliber on your own if you have know how of hardware?, is there an existing part list of antminer s9 out there? and is it cost effective to build your own miner from scratch or just purchase one?. please bare with me for I am a noob trying to L2P. Thanks
