Which (1 or 2-story) frame to use for 7 GPU rig?

I've recently bought this 7+0.5 PCIe slot motherboard. I want to assemble 7 or 8 GPUs rig. I guess for setup not to become ball of cruft I need some mining rig frame. Which onr to choose - where GPUs are stacked in a single row/story (like this), or in two rows/stories (like this)?

I've seen that at least on the locallama people with 8 GPUs or above use 2-story frame. If you built those, what are the difficulties? If you haven't maybe you've seen a good youtube video or an article on that?

The 2 story frame (AAAWAVE) one is okay. I have some advice posted for it here.

Single row vs two story, biggest thing is it's annoying if a problem arises with lower row and you have upper row in use too. You're doing a bit of a re-build to get back in there. With a single story, you might be able to access the motherboard by just removing the few cards above the spot you need. But to the AAAWAVE two story one's big credit, everything is the same screw size so that helps. Pulling apart and back together is fast. I have my GPUs on pcie 8 pin to 2x 8 pin extentions, they have enough slack to with the front fans/bar off just be pulled forward and layed out on the table in front of it. It would seriously be sore finger time unplugging and replugging in 40 pcie 8 pin connectors...

I'd just go with whatever fits your space, wide one story ones are wiiide. So figure where it'll go when you're done building it on your bench or whatever to decide this one. And what length pcie risers too.
