Favorite portable computer bench case?

To just sitting on top of a anti static mat...

There are options for how to manage a test computer.

Do you have a preferred case that is portable, stackable, and still easy to work on?

I've thought about Fractal cases but they are on the bulky side of things. I've thought about a 4U case Silverstone rm44, but then the components are hard to access.. and noise goes up
