I missed that, good call. Well the Bitspower GPU block is 154mm wide and the MSI Gaming Trio is 140mm wide. I've never used a GPU water block before, but is it safe to assume we just use the water block size to determine overall dimensions?
That said, I think with 159mm clearance and a 154mm water block, the 5mm difference won't be enough to fit the 8pin connectors to the GPU. I might look at the less thicc 2080's (Asus/EVGA)
