I have the Silverstone LC-10-M case, and it comes with an IR receiver built into the VFD on the front of the case. Unfortunately, it is USB header IR which I understand does not work with LIRC. My motherboard does have an IR SIR/CIR header. I was wondering if anyone knows of or has a built a USB to IR header adapter ?
I suppose I would still need a USB pass through as well to drive the actual VFD display.

Rich,
I use the motherboard irda port, in SIR mode. Works like a champ. Almost the same field of effectiveness as my TV, which could probably be improved if I got it closer to the smoked glass front.
I built the darn thing from a simple IR receiver (Radio Shack 276-640) and two capacitors (10uF and 100nF) between VCC and GND. It's on a small perf board, but if you're clever with your soldering, it could be done without. The hardest thing to come up with the the cabling. I happened to find some scrap from work, but you may have to find something that can be chopped up to plug into the motherboard irda header. Check your motherboard manual for the pinout of the header.
I looked briefly on Maplin's website, but was unable to find a good equivalent for the IR recevier. It's a pretty generic part, though, so one would think that somewhere in the UK there would be something close to this. Of particular importance is the operating voltage (should be wide) and the center frequency (around 38kHz). It's basically made to receive IR signals from a home remote control.
After that, it was just a matter of turning the port on in the BIOS (replaces a serial port) and adding the following line to make.conf before I built lirc. (Mine is a Gentoo system. For others you'll want to figure out the proper way to build it.)
LIRC_OPTS='--with-driver=sir --with-irq=3 --with-port=0x2f8'
