I had a mini-ITX case where the AGP port (yes, it was a while ago) was right up against one of the walls, so the GPU fan was pinned against the wall. As expected, the machine crashed every time I started up a game. We fixed it by drilling holes in the wall right where the GPU fan faces it. The next version of the same case came with an array of holes drilled in that exact same spot, so I guess we were on to something.
