https://litecointalk.org/index.php?topic=14956 Seems like user hashware already has these and posted a few clips of the devices...assuming this GB is the same as what he ordered and shows in his videos, it looks like it comes with PSU, the devices, and various cables...I think the only thing I didn't see in that video was a powered 10port USB hub.
Thank you very much.
I hope it still comes with the power supply if you ordered 1 unit since it looks like when this guy hooked it up to a 12V PSU it fried his unit!
