Depends on how you plan on patching the opening in the back of it. I believe youd have to really cut the heat sink down pretty far in order to get a fan in there. If you extend the back to accommodate for it then it depends on how much of the inside you cut out. A medium cut would fit fine I think. Im using the same shell but I extended it with a polycase.com case the ag-85. Look at my worklog to see what I mean. I had to cut most of the back out to make up for the height of the mobo, heatsink and fan. A modified minimal/medium cut will fit I think, though it may be tight how I want to position it.
Blargs pic of his cut would definitely work though.
