No, I haven't seen it done, but would like to put the idea out there.
I've noticed the price dropping on CRT Need for Speed cabs lately and saw a NASCAR cab with 32" LCD sell for around 2 grand recently.
http://www.ebay.com/itm/Good-Working-Global-VR-Need-For-Speed-GT-Sit-Down-Racing-Arcade-Game-/230978311489?pt=LH_DefaultDomain_0&hash=item35c7615541It's a lot of money and I'm not a fan of the style of the cab, but these games contain the USB immersion PCB that interfaces with a standard Windows PC.
People have successfully used that PCB to interface their Happ ffb setups and ECCI uses it for their wheels.
So it
should be pretty much plug and play. Install the immersion drivers on your PC and drop the PC into the cab...done.
Only downside is that this particular game had the sequential shifter instead of the six speed.
Not sure about the monitor resolution, etc.
I haven't done all the research, just noticed a good price on the NFS GT and put the idea out there.
You could sell the PC and security dongle currently in the machine and recoup a little.
