I bought 6 Neptune cubes, as well I have 2 controllers. These things are garbage!!  I spent a little chunk on them, and really want them to work. Is it possible to send them to be repaired??  If not they are all for sale. I believe the control are Jupiter control. I have 2 1200w psu"s with breakouts and all cables, 2 sets of 10 pin cables...short and long.

Id rather they get fixed...but if I cant make me an offer... They work,then they don't... having to reset all the time as the hashrate drops ,or some cubes get kicked off.
