Yeah, you gotta love that setup. I'm afraid I'd lose a finger, or catch my house on fire

I actually have a 4-card bitcoin mining rig similar to this wooden frame setup, but for the Octane box, I wanted to try to get it all in a case.

Yeah, that sounds like my system. Do you think watercooling is an absolute necessity or a "nice to have" feature?

Nice, thanks. Just speccing out my dream Octane box

Has anyone come across a motherboard that will allow 4 pcie x16 double height graphics cards to all be installed side by side?

I've come across a lot that have 4 slots or a combination of x16, x8, x1, etc., but from what it looks like, double height cards would end up blocking 1 or more of the slots.
