So...I've gotten the itching to build a box mod and I was wondering if anyone had thoughts on using an ABS plastic project box as opposed to an Aluminum project box. Are there any +'s or -'s for either in a box mod application? I know that ABS can break easier than aluminum. But then aluminum is going to be heavier. I was thinking of doing a DNA chip with 1-2 18650's. Nothing terribly fancy...just functional.
