Thread: Advice on filling 420 HP
Looks sweet!
Since you're new to this, my suggestion would be to start with one row's worth of modules... cover the remaining blank space with blank panels (or make some out of thin wood or even cardboard). Take your time, get to know that row of modules, then after a few months add a couple more toys... it's easy to go too fast, especially with a large, empty case begging to be filled.
