Thank you so much for your thoughts on these cases. Your setup (LMB & LMS9) is exactly the combination I am considering. They are incredibly economical and available at one of the modular shops I usually order from. I definitely do need to go through my planned rack to break down the power consumption per row. Thanks for the reminder and details about the LMS9 power supplies.
I'll probably invest in these new cases in May, so I'll let you know if I have any more questions in the meantime.
I know what you mean about packing the racks with modules so quickly. After looking through your module reviews, I'll probably buy a few more. ;)
Thanks again for all of your input, and for making the modular community a welcoming place.
