I am a mini-ITX fan,of course I think the card is great if not overpriced. I even a few years back cut up a G2 series Shuttle so I could fit an HD5850 in it - it kind of worked!
Even worked on an ammo-box system with a mate using a single slot 9800GT which ran stupidly hot.
I nearly bought the GTX970 Mini myself,but ended up buying a new tripod and gimbal head for my dSLR,so have no monies now!
But guess what,I bought Shuttles when they were like the best SFF systems and they were massively overpriced and flawed too.
Some of the most vocal people against the card,well to put,I have seen them even care one dot about SFF systems(could be wrong),and thats why the GTX970 Mini threads were short - only people who cared about SFF systems posted in them.
Yet at the same time,you never saw any of the more vocal AMD fans jumping and starting a war about them.
But more importantly,why can't we have some discussion about things like the Powertune on the card,which seems to run reasonably well,compared to what we saw in the R9 290 series?? It does seem a genuine improvement in implementation over the R9 290 series.
Even the fact that AMD managed to tame a GPU with GTX980TI levels of power consumption down to more GTX970/GTX980 levels,especially as it turns out AMD has gone the more hardware route in certain functions which adds power consumption,where as Nvidia gone more the way of better sw optimisation(and better effiency I suspect),to gain similar functionality.
Not to say Nvidia could not do the same either or the Nano should be MUCH CHEAPER,but still...
