Making a block diagram

[Blakeasd]

Hello,

I need to make a block diagram like this one. I'm looking for an app that can do this in the fastest way possible as I need to finish it by tomorrow. Does anyone know of an app that I can accomplish this with relatively quickly? Will the latest version of Apple Pages work for something like this?

Any advice is appreciated!

Thanks!

My first guess would by InDesign, made by Adobe. It is expensive.

I could do that in minutes with Powerpoint.
