Istick 100w re-boxing

So I have a istick 100w that I took on a trade for other vapour related things I no longer use. I was wondering if anyone knew how hard it would be to take it all apart to put it in a different, custom box. I’d also want to change the buttons from the ones on it.

I have 100 I stick. I had to fix it cause the 510 connection can break inside. It got loose so I used opoxy. Check it out.
