Just a word of advice, that section of your second row with a bunch of 2hp modules will not be fun to use. If you have to have modules that small, it will be best to spread them out around your rack if you actually hope to make use of them. Better yet, invest in a larger case so that you can utilize modules that have some actual room to tweak knobs and plug cables in, and only use tiny modules to fill gaps. You will thank yourself later.
Have fun and good luck!
