The Samsung Fridges require a 50mm gap all round. Actually most fridges require that amount of space.

This is pretty standard, unless ...... you get higher end fridges like Sub-Zero, Gaggenau etc.. These have ventilation slots either at the top or bottom of the fridge. Perfect for a built-in situations. One mid-high end alternative would be Bosch. I checked out the Bosch Kan 58A45 - Width 900mm. (Cost $3,399 @ Courts) 4 Tick energy rating compared to Samsung's 3 Ticks
