4x 280x waiting on a 290x so I can add another.

What temperaturs do you have there? And what PSU???

coldest one: 67 and hottest one: 75.

Setup:
Proc: Intel Celeron G1620
Mobo: Gigabyte GA-Z68X-UD3H-B3
RAM: Corsair Dominator CMP4GX3M2C1600C7
PSU: Corsair Enthusiast TX850M
Seasonic M12II 750W 80+ Bronze
GPU: 3x Dual-x 280x 1x Vapor-X and in a few days a Gigabyte 7970

I'll be running the Dual-X's from the 850 Corsair and the Vapor and GB from the 750W, which will also power the Mobo and risers.

I'm planning on building this in a few weeks:

It'll run 7 280x's on 3 PSU's cooled by 6 200mm fans. All arranged vertical to create a natural flow upward.

I plan on something very similar. My drawings allow room at the back so the motherboard can mount inward though. Also I'm only using twin PSU's. It's a 5 card 290 setup (running in a previous frame design), but soon to be a 7 card 290 rig.

I assume you're going for USB PCI-e risers? You might need to make it a bit deeper to allow for cable management.

Keep in touch, look forward to seeing your work! Seems building vertically is in the minority here!
