Dude i think you need more practice before you atempt to mod another case,I've never had the tool's to really mod but i've alway's made sure it looked half decent,My mod tool's only consisted of a drill - tin snip's and a couple file's,Just using those i've made fan hole's just as good as a decent hole saw,Now that i have my dremel and a couple other new tool's i don't have the money for another case to mod
