Is my rig/order missing anything?

Riser cables and a proper frame to mount 7 GPUs. This bench table does not seem suitable for something like this, better go with something like this: https://www.newegg.ca/black-rosewill-r20...6811147285

You should also opt for more than just 16 GB RAM. Recommendation is RAM >= total VRAM of your GPUs, so more than 77GB in your case.
