I currently have the carpc linked up to my house wifi and that works fine but ultimately since the house wifi system is actually 54g (and netsumbler don't work with usb wifi devices

), I'd like to get a 54g pci card that has a detachable antenna for the carpc.
I do already have a spare belkin 54g PCI card (F5D7000uk) but here's the problem.
The CarPC is in a Procase 3677 so whilst the Eden800 works fine with this card the width of the Belkin Wifi PCB (already removed the metal plate) when sitting in the PCI slot is 4mm higher than the rest of the casing and hence the lid don't fit

I've looked and belkin are very miserly with the pcb as there is no way of shaving the pcb down so that it fits
I have tried a ribbon pci extender but there is just not enough room inside the case to orientate the pci card.
So the question is (as trying to get this info out of retaliers tend to get met with an expression that I've grown another head) any of you guys know of a
54g PCI card that has a PCB of 40mm or less width excluding the pci edge connector?
Here's the belkin one which you can seen the green pcb area on
Cheers.
