ASUS Maximus Formula SE

[palehorse]

3 quick questions:

1) Can you run the Maximus Formula SE with simple air-cooling, or is water mandatory? If using only air, do you need to mod anything?

2) Is the standard Maximus Formula (not SE) available online for US customers? All I see is the damn SE everywhere...

3) Would the P5E be better than the Maximus, even the non-SE, for someone who doesn't want to use water?

I'm helping a friend with a new build, and he doesnt want water-cooling... So thanks ahead of time!
