I hope for a new release too. There is a market for a silent miner.
I feel like the real miners don't really care about a bit of noise lol and I say that because if you're really in it to make money you are going to need a lot of miners and a professional operation so noise is not going to be a big concern of yours. Just my opinion.
The point of the R4 was to build a miner that could be run by the home miner enthusiast. That's it. Let's face it, home miners haven't made a profit for some time. It's just not possible. Still, there is a market here.
