Anyone know of any PCI brackets that have a molex and 4-pin fan connectors for passthrough. Looking to control external fans from an inside fan controller, ideally pass through an Aquabus connection.

Closest I can find is 'Phobya PCI slot cover 4Pin Molex & 3x 4Pin PWM fan plug' but is looks to use only 3 pins on the molex + custom traces to the fans.

I was thinking could purchase this and cut the traces and solder on some fan extensions, but ideally could just purchase a bracket.
 
If you're content with soldering, you could probably just make something yourself. I presume you'd want all external fans to be in sync, so all you'd need are 4 wires exiting the case: 12V and ground from the PSU for power, and Tach and PWM coming from the fan controller. You can then chain the fans together by whatever means is tidiest for you (obviously you only want 1 fan connected to the tach wire), sleeve the 4 wires from the case into a single unit and just drill a hole into any spare PCI cover for the cable passthrough.

Fan headers and stripboard are 2.54mm pitch so you could solder up a fan splitter PCB in a trice for little money.
