Corsair 100R Windowed Fan Configuration

What is the ideal fan configuration for a Corsair 100R Windowed? There is space for 5 fans. 2 front, 2 top and 1 rear. On an all air cooling build what is the best config to have the fans in? is it worth having all 5 fans?

How about this: http://www.corsair.com/en-us/~/media/F5A7BB6C9128440DBA79A654E086C006.ashx?w=780

I don't like cases like that. Not enough spots to put intake fans, and way too many spots for exhaust fans. The link that @Nexxsys posted is pretty much the best you can do.
