Very cool idea! I would love to see it work out, but I agree with QinX that you'll probably not be able to cool the thing effectively enough for a 970 to work. A 950 sounds more reasonable. With it you could also dismiss the additional DCDC converter and just go with a single one like H2O-Micro did.It also seems that 25mm are a little too optimistic. Yes, the thin mITX board you've got modelled there has a rather low component height on the back, but you'll still need about 3mm of clearance there. Add to that the ~1.5mm board, 20mm primary component height, 1mm clearance there and 1mm (probably more) outer case material, and we're already at 27.5mm. Still impressive, though.
