Yes, you will have them filling then draining then filling again if you have a wavebox going in there. I helped set one up on a 210g and it had dual overflows but they were not corner overflows. You could hear the sloshing and slurping sounds alternating between overflows until we did his with the "Herbie" method or siphon/emergency drain method.
Do you plan on using BeanAnimal's design for your drains? I would think that you would want to keep the overflow as small as possible to make more room for rock/corals and keep it inconspicuous.
FYI, I have run 1,500 gph through a single 1" PVC drain when using the siphon method so if you have 2 drains plus 2 emergency drains you should be able to keep up with roughly 3,000 gph without upsizing your drains to 1.5" The connectors and pipe gets a lot more expensive and harder to fit in places as you get over 1" so that's something to consider.
If you are sure you like closed loops that's fine but consider the 300watt pump that CleveYank mentioned for 1700gph of flow can be achieved with one powerhead at 20 watts. They may be a bit uglier but you can move powerheads up and down in the water column and aim them almost any direction. If you have a closed loop you will still see the ends of the tubes unless you are planning on drilling the bottom and doing the whole "inside the live rock" plumbing system.
In my opinion a few small powerheads properly pointed and partially hidden flowing 6,000 gph at 60 watts is more advantageous than a single 1700gph pump running at 300 watts and there is no place that a powerhead can have a leak like the plumbing you would have to do on a closed loop.
Are you planning to have the sump in the stand or are you going to the basement?
