It's debatable about getting the LC. For free you can afford to take your chances with it, but you take a big risk if they want money for it. Those old LC's suffer from leaky capacitors the same as the SE/30's so if it's been sitting for while with leaks the motherboard could be rotted away in places. So basically if it's free, go for it, you have nothing to lose as it could be repairable or at the very least you might get some usable parts out of it.
