Fresh Install Of Mountain Lion on External HD

I would like to do a fresh Install of Mountain Lion from My new late 2012 iMac to a bootable external hard-drive.

I know about Supa Dupa etc , but I would like a FRESH install & not one that has some Folders,music etc

Any ideas if this can be done ?


Thanks Vince

iMac (27-inch, Late 2012), Mac OS X (10.7.3)

Restart with the Command and R keys held down and install the OS from there. Click here and scroll down to or search for 'Installing OS X on an external storage device' for more information.
