Anyone know what coating is on Bitmain's units (at least on their newer ones, S7 onwards)? It's tough as nails. I'm wondering if it's an epoxy.

Will a 2oz copper pcb be enough for a PSU breakout (~1200-1500W)? The two things making this difficult for me to calculate: I'm not sure what an acceptable temp rise would be, and I'm using copper polygon pours (rather than traces) for 12v and GND. Anyone with knowledge able to provide some feedback? Thanks in advance 

I placed an order from Innosilicon a week or so ago and have not received an updates on shipping nor order status. Maybe I'm being paranoid about this, but I'm reading that these pro-democracy protests in Hong Kong are temporarily halting certain businesses, banks, and shipping. I'm not sure where Innosilicon Technologies LTD is located, however I was under the impression that they shipped out of Hong Kong. Does anyone know anything about this, or perhaps, can someone who is in Hong Kong comment on this? 

I've tried numerous ways to set this node up... on my own LAN, a VPS, or even when I solo mine without using P2Pool. My miners always sit at Worker Utility of 0. I have the wallet fully synched and I believe the config file is set correctly. Does anyone know why WU stays at zero? I've seen the question raised before but no clear answers. Thanks.

Can someone help me identify what Zeus miner I have here? It is supposed to be the X6 Lightning (~40MH/s model). I had to RMA the original Lightning bc it wasn’t hashing. After a month of waiting I finally got this unit in the mail, except it was not mailed from Zeus but rather from the distributor (in the USA). A few things tip me off that this isn't a Lightning: it has 4 PCIe connectors (not 2), the sticker on the heatsinks reads “8”, and the voltage sticker reads 1.1V (I thought the X6 Lightning was lowered to 1.05V). 

Can anyone identify exactly what they sent me? Many thanks for your feedback and time.

So I sold $600.00 on BTC-e and cashed-out via USD PayPal. A few days later the money arrives in my PayPal account, however, the day after receiving the money the funds are put on hold (that is to say, subtracted from my account). The email I received from PayPal states: "You have received a payment that we believe may not have been authorized by the PayPal account holder..." While awaiting for PayPal to arbitrate this dispute, I'm reading tons of negative feedback about BTC-e fraud and my hopes of receiving these funds unscathed is rapidly diminishing. Is there anything I can do (or not do, for that matter) to help my odds at this point? Thanks for your feedback.
