Dell Dimension rear fan mount (4600, 4700++)

This is a fan mount for a Dell Dimension 4600 or 4700. Might fit others, you should check the measurements in the STL for your Dimension case. It houses a 92mm fan up to 25mm thickness and it's designed to use the original rubber mounts, but screws should work too.

NB: This does NOT replace the original for original hardware, since the original has a green air duct that lets the airflow over the heatsink. This is only for repurposing the case, such as building a sleeper out of it which I did.
