FYI, I discovered that the slightly newer versions of the ATI graphics cards have really nice copper heatpipe heatsinks in them. Unfortunately the mounts are different, so I made a bracket to convert the hole pattern. This works great in the MDD as it also blows the hot air out the back instead of stirring it around inside the case. It would probably also work on the Quicksilvers but you'd loose a PCI slot.
Anyway, I don't know if anyone tries to upgrade the cooling on their graphics cards, but this really helped to lower the temperatures on the x850 and FireGL X3 cards that I've done it to.
