It's a Pump/CPU-Block combo, with a small res as well. This wouldn't go in the 160x65x30, it would be the CPU block.
Sorry! Didn't even see that it was a cpu block as well! There is about 37mm clearence between the top of the motherboard and the bottom of the PCB so while the pump would fit, no fittings would. What you could do though is move the graphics card up one slot (given that the card should now be a single slot card) and that should give you just enough space for 90 degree fittings.
