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

thingiverse

This is a custom-designed mount for use with Dell Dimension 4600 or 4700 systems. It may also be suitable for other cases, so double-check the STL measurements before installation. The design accommodates fans up to 25mm in thickness and utilizes the original rubber mounts, but screws can also be employed. Please note that this is not a replacement for the original hardware, as it lacks the green air duct found on the standard model. This modification is intended for repurposing an existing case into a sleeper system, which I personally accomplished by creating a custom buildout. The mount was created using Sketchup software and takes precise measurements from the original part to ensure accuracy. However, it has been shortened to accommodate 25mm fans instead of the standard 30mm size, thereby providing additional clearance for large CPU coolers within the case.
