2 projects which looks like to reach the goal :
-
http://ltcgear.com/ less power comsumption, but the only way to have a ROI on it will be to mine with them many months
-
https://alpha-t.net/ less power consumption and a similar Hashpower regarding a rig with GPU (6x7970)
lot of pre order but do it will be a "BFL-like" ? We'll have the response during Q2/3. Add the time of all the deliveries we go through 2014.
