Man, wish I could be so lucky. I've been looking for a BC one at an affordable price. From what I have read:
-Use MultiMan on Custom Firmware to change the fan speed of the PS3
-Add new thermal paste to the CPUs.
-Replace the NEC/Tokin Capacitors.

This should be done before it YLODs, because once the YLOD occurs thats usually it. Let me know if you are interested in selling it.
