yeah, good call, I did think of this a while ago but found out that some versions of s9's dont run without all boards present and exactly the same board revision number, I know this having used a number of units myself and swapping boards around, but cant see any thing definitive on any website, at first I thought it was a batch of bad unit I had, but new ones act the same aswell, have not seen anyone else complain about it so I am at a loss as to whats happening, I am currently chatting a a few people with units I am hoping to nab, I am not worried about efficiency, or noise as I mainly use remote connection to work setup so I dont actually have to be there 90% of time, I heard of the s7-LN but for some reason they sell for as much as a S9 here in UK ^^ so I would rather "one board" a S9 if I can get away with it.
thanks for your response, I should be done if one of the people I am talking to pulls through for me.
Yea I keep an eye out on ebay aswell (I'm in the UK too) and prices seem high on ebay all the time, even for really for efficiency gear. Anyway, fingers crossed you get something
