Multi Projector Setup 5x1??

[Hatlesschimp]

For some of these configurations i would have to run with LED projectors so i can have a portrait projection.

I'm leaning towards the ASUS B1M because it is a short throw so I can project from the rear.
Its also 700 lumen LED projector. Im not sure if it will do 3d or 120hz at this stage.

So purely for gaming which would you choose?

I'd do 5x1P just because it's not been done before on a consumer build. It would be breaking new ground.
