Building a stand this weekend

Using a 2x12 and extending it past support on the back/sides laying flat could possibly lead to snapping the 2x12 down the grain

Ya I thought about that so I was planning on adding some posts to support it unless you can recommend anything else?

Make a knee brace for it to support the outside edge down on a angle into the base.

I can go straight down from the outside edge too. Or is a knee brace better because it's tied to the stand structure?

You could support it many different ways. Whatever you find suites you skill set for building and looks the best to you.

My recommendation based on what would look the best and in my opinion give best support for what you require would be to find very straight pieces of wood to make a knee brace out of, go full length with the pieces. Bevel the top end bottom edge of these pieces so they sit flush into the upright supports and to the top plate you intend to extend out. That will support the top plates the full length, give them the rigidness required to support and distribute the different stresses on the top plate you will be subjecting them to as you work.

I would suggest adding 3/4" plywood (or even two sheets!) as well as a third 2" x 6" in the middle.

Using this design you will find that the centre is restricted in terms of adding a sump.

As mentioned, depending on how comfortable you with woodworking, knee bracing will give you a little more room and be almost as strong as posts.
