Not sure. Does anyone have a waterblock that they can measure?
Edit: Wait, I'm on EK's site and the blocks don't have that piece on them that puts the ports off to the side - I assume that's an add-on? So you could theoretically use 90-deg fittings on the GPU block without the fitting, and route tubing in a similar fashion, a bit more out & to the sides than the image above (if that makes sense) and it'd be more space efficient. The fittings might protrude a little from the bottom of the case (out the drainport cutout) since there's only an inch between the block and bottom of the case but it should work.
Does anyone know why EK doesn't have the more common style ports that are accessible from top & bottom? Seems like a really limiting "feature".
