Fantastic response, thank you very much for that. You are correct that the GPU AIO is also 240mm. The more I consider this the more your option 1 makes sense. 3 intake fans on the front supply cold air front to back. Bottom rad as an intake pushes warmer air up. This air will be pushed to the back from the intakes in the front where it should be exhausted out by the back exhaust mounted in the upper most position. This leaves the top rad as exhaust to suck the cool air coming from the front of the case. I think I'll try this first.

Hi guys, just wondering your thoughts on fan directions for the two AIOs. One will be mounted top and the other bottom. There are the three intakes in the front and 1 exhaust in the rear. My initial thoughts are to mount the CPU AIO top as exhaust, and the GPU AIO bottom as intake. Pulling air from the front and bottom then pushing it out the top and back makes sense. I don't think the air flowing over the top AIO rad would be very warm with this setup, but I'm looking for advice. Also it's been a while since I did a new build. Should I replace the factory thermal paste for the MX-4 I have on hand? Thank you!
