https://canaan.io/product/moose/The Moose is an all-in-one mining solution which contains twelve units of AvalonMiner 841 with PSU and AvalonMiner Controller, all the necessary cables and plugs for running these AvalonMiner 841 are connected before shipping.
All you need for letting a Moose start working is to plug-in the power connector and the internet cable, then have a coffee. The Moose is stackable.
I think these are neat and the price is on point.
