Metal Briefcase

I am a techno geek, I love technology and I use it almost every day. The problem is though, I like travel too, and I want to keep my stuff in a suitcase metal. With my addiction to travel, I was wondering, is it possible to travel on airlines with a metal briefcase. I mean I understand there are rules, but I'm not even sure. So, is it allowed?

Yes, it is allowed. There are no restrictions on the metal towel other than size requirements. An X-ray machine can see through a metal briefcase very well.

I do not see why not! I do not see why anyone would take a metal breifacse well! I na not even know they have briefacses metal!
