I was thinking of building a similar rig, but is it really worth it to water-cool radeon vii. The temperatures dont seem to be that high.
With watercooling I can fit 4 GPU's in a "normal" ATX case using PCIe x8 connections to each GPU directly from the motherboard (x79 chipset). If I am able to lower the temperatures with 20-30 degrees Celsius I will almost definetly be able to push the clocks higher at a certain voltage. I am also hoping to get the noiselevels down. This rig will hopefully also do some Blender rendering when not mining.
