If your GB stated $290 it should be $290 and nothing more regardless of power consumption. Those were the terms the customer agreed to.
People paid for the SP30 only. The hosting was a bonus offered to anyone that wanted. It wasn't enforced or anything and I am sure that it's based on the power consumption. The good thing is that I don't think that it will vary a lot because we can't push the PSUs a lot more than 2700W.
Also, Spondoolies emailed customers about a month ago asking for a commitment to either hosting or free shipping. If you didn't opt for hosting back then, it may be too late to get those prices. The fact that bobsmoke is asking now what the price is suggests to me that he didn't purchase it then, which is why I listed the rates Spondoolies is currently advertising.
The crippled Rockerbox ASICs might pull less than 2700W per SP30, in which case customers might get a rebate from their hosting provider. Or they might not. Depends on the DC's policy, I guess.
thanks! btw do you know why Spoodoolies says there is no customs fee when shipping the SPxx from Israel to US? how do they import the machines into US?
