As a beginner as well to modular, my advice is to buy the largest case you can buy, the bigger the better. I recommend a 9u or 12u case at the bare minimum. That way you won't be squeezing tiny 2hp modules in it. Thus far, I really like the MDLR 12u and 14u mobile cases they have 1u rows of tiles so you can add the Intellijel utilities to those and save the space for larger cool modules. Pamela's New Workout is great. I have mixed views on the Disting- lot of menu diving and not the easiest to use for live performance or beginners.
