I had everything up and running yesterday! I wanted to wait 24-hours before I posted just to make sure everything went well. This was easily the fastest ASIC setup I've dealt with. The power supply came pre-wired (Though I had to wire up my own US 110V power cable) and while it's on the small side, the included brushless fan moves quite a bit of air. I'm not worried about the PWS at all.
As for the blades, I have tried hashing with both the newest versions of Minera and the WiiBox. Much to my surprise, and despite its lack of data capture, the WiiBox is out-performing the RasPi by a huge factor. I see a stable
11MH at the pool when using the WiiBox.
All together, I have been VERY happy with my experience at X-Hash. What few questions I had were always answered in a timely manner and everything was packed very well. You can bet I'll be ordering again. Better customer service and faster shipping then all of the US distributors!
