Definitely, if it's going to be your only system, DON'T get a Palette. Get a larger case (the Mantis is great... or Eowave has a new 7u case that is reasonable) and give yourself room to grow.
I love my Palette for when I want to focus on a handful of modules... but as a full system, it would get dull fairly quickly, no matter what modules you put in it. It's a nifty case, but it plays a very particular role.
