No, the miner designs are not finalized.
However, we have produced a v1.0 design, as viewable on the website homepage. It has the ability to stand up like an obelisk, or lay on its side like a more traditional cryptocurrency miner. It has perforations on either end to allow sufficient airflow to travel through a dual-fan, push-pull system.
The miner will be approximately 8x8x14 inches, but this is not yet finalized.
