Just wanted to chime in and say that the current price listed for the 2.4Th/s nTek miner is set high right now because we are currently working out some details for the production cost. We are getting the latest prototype PCB's back this week and will be able to better test the cooling system. Worst case scenario we will need to use liquid cooling on the top of each A1 chip.
Based on further testing we may likely find that liquid cooling is not needed on the top of each A1 chip. Also our engineering team is working on a new design based on liquid cooled copper heat pipes and aluminum heatsinks adapted to the top of each A1 chip. Over the next week we will have a much better idea of the price to add the liquid cooling to our current modular heatsink design.
Wouldn't it make more sense to wait until you have an idea of how much it will cost you to build one of these before you advertise a price?
After seeing many 3rd party A1 boards, you never quite know how they'll turn out. Those chips are horrific to try and remove heat from.
