Update:
Been putting in work with a few different manufacturers to get the prototype off the ground. I came across a few design issues that needed to be changed. Working on those now. I also have a few design changes that I'd like your opinion on, below.
Power Button: I decided to go with two different options on the power button location. One placed on the front bottom that wouldn't be visible, but would require at least 15mm tall feet so that you could access it, and one located on the rear panel. I can leave cutouts for both without affecting the appearance, so it could be left up to the end users' preference.
Front Panel: I created a "floating" front panel cover that extends the case length by 12mm, but it covers the off centered central air chamber cutout for a cleaner appearance while still providing airflow from the front. Let me know what you guys think.
