Are you using a PCI adapter for the Apple wifi module there? I'm just looking at the 3 antennae and have seen similar adapter cards on ebay.
I'm wondering if one of those would work with a BT/WiFi combo mini pci-e card? Ebay search isn't working right now but when I was looking up mini pci-e cards from MacBooks there was one which had wifi and bluetooth on the same card. It appeared to have 2 connections (one for BT and one for WiFi I assume). I was thinking of getting a pci-e adapter card with 2 antennae and using it with this combo card in an upcoming hack build.
yes, i'm using apple wireless card (bcm4322) with mini PCI-E adapter and Apple Bluetooth card from MacbookPro connected to USB on MB. I think that you can't use combo card (Wi-Fi/Bluetooth) from Apple with mini PCI-E adapter because it has 18 pins, PCI-E has 26 pins, so they are not compatible.
You should flip the CPU fan around, it's blowing the wrong way.
air direction of the cpu fan is going from inside of the pc to front out
