WOW, do you really need 3 cards, LOL... Cool bro, I really appreciate if you post the pictures and maybe let me know where I can buy the LED strips at in RED!
Okay as promised the info
the led's and yes you can get them in red and they are 12v can be found at Hobbypartz
so all I did was take the screws out of the back and stuck my Led's to the bridge removed the resistor and added a 4th led simple math 4 led's at 3v each = 12v
Replaced the face on the bridge ran 12v from the psu and there you have it
and the 3way bridge has spacing of this
or
hope this helps
