I have had a few dremel experiences and it is some what time consuming as you got to be extremely careful not to go overboard.
I did them for other people though so i dont have any pics. Sorry in that regard but give me an idea what you want to do.
If I can help with any Q's, let me know.
I have completely stripped out the entire case including all of the brackets and redone them to accomadate 6 hdds and 2 rom drives, and 4 fans.
2 of the 3 Ive done where mid tower cases. Full towers are best for this. That way you can add a second power supply for the lights and what not, and still have all the room you want for other stuff. This use to be my favorite pass time but i got away from it for a while as its hard to make any money for the time it takes to pimp them out.
