respect, Stefan.

at first the price (€475 for pod on bitshopper) looked a bit high for the hashrate compared to for example a second hand Avalon841.

But this is silent unlike the Avalon which needs to be put in a garden cabine and probably uses 1300+W for 12TH.
Yours at 3.5TH/200W would need almost half of the Watt for the same TH speed.
Ok, it will be expensive at nearly €1900 for 4 units but it's still silent

It's also a bit higher priced (€75) than the Terminus R606 (which I also have and runs around 880GH without issues for months now)
but it's (written to be) 2-2.5x as fast at nearly the same draw (100 vs 125W)
and 4 times faster at twice the Watt draw (100 vs 200W) in Turbo mode.

which means this product isn't as bad as someone claimed on the first pages and as stated from the beginning ideal for home use
and can be placed on your desk without noticing that it's on (if the sound level is about as low as the Terminus R606).

I got notified by Bitshopper's mailing list about this but it was already sold out when I peeked at it.
