I worked at a couple of Auto Body Shops when I was younger, it's much cheaper to do it yourself. Checkout some of the Guide's Bill has posted over at his Store. There's really not much of a difference between cutting an access hole or a window
I finally picked up a can of compressed air and some zip ties to do my case again since i swapped out the mobo. Sorry for The quality of the pics being bad.
In the first pic there is a fan wire running behind the mobo that you can sort of see *near the top* that is not there though, i pushed it to the side for you cant see it at all anymore.
I can't remember what the size restrictions are for these pics, so sorry if they are too big.
