Not sure if this is the right place for this but I am looking to gather parts for a DNA40 mod and I'm wondering what the options are beyond the Hammond project boxes. Seems like there are a lot more options for the extruded enclosures with removable plates on the ends rather than the back. Are these viable? Mostly wondering how to handle an 18650 inserted up through the bottom since the normal sleds obviously wouldn't work. Not this one necessarily but this style.
