I havent done the best job of documenting my progress on my case, but heres some pics anyways. I started out with a POS Hewlett Packard case, much like the one Defyant used in one of his more recent mods I believe. I used a hard 2 part epoxy similar to milliput and a dremel to get the organic looking part of the case sculpted.
Yes, i know, im a cheap SOB for copying mashie, but i couldnt really resist. this technique turned out so well on his mod i thought i would give it a try on mine.
