Update: I've finally had a chance to run a 28-hour print and found that the inside of the control box was barely warm at the end, even considering I use a fanless power supply so it also relies on the 60mm fan. I think that with a 60mm fan on the back it's safe to say you should have ample cooling with this design either way. In case you're doing a spec comparison the fan I'm using (GELID Silent 6) has a air flow rating of 16 CFM / 27.2 CMH

That looks pretty slick! Is that a DB25 breakout board to connect to the printer itself? I'd love to see a writeup of how that's working.

That is exactly what you are seeing there. It works very well but I learned the hard way that running any high-current through there (in my case, the extruder) was a bad idea. Anyway, DB25 is more than sufficient for X, Y, Z, and Extruder motors, as well as end stops, a fan, and if needed a couple more sensors. The trick is to use a common ground for the end stops on the plug so that you can save a few pins.

I have another 6-pin din which can handle high current which I use for the extruder and the bed as well as another 12v line for an always-on fan.

I was wondering if Amphenol connectors would work (old school SCSI and Parallel connectors) - These are rated at 5 amps per pin: https://www.newark.com/amphenol-commercial-products/57-20500-7/mini-d-ribbon-connector-female/dp/88K2173

Just to be safe I recommend higher amp plugs for the heavy current. I use these for my hot bed and extruder with no problem: https://www.amazon.com/gp/product/B07GZBXGR7/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
