Do rack power amps fit into shallow rack cases?

[Marmoset]

I'm going to buy a 4u rack case, and at the moment I have an ADA MP1 and a Rocktron Xpression. Both of these will fit into one of Gator's shallow rack cases, which can fit units up to 360mm deep. Will a typical rack power amp fit in a shallow case, or should I buy a standard depth case instead?

Thanks for the help, I'm still learning about rack stuff

My old Tubeworks MosValve would since its solid state and wasn't really any longer than a MP-1, doubt many of the all tube ones would though..
