The problem is eBay dumpster finds like this you don't what the history is or who has worked on it. Can only suggest you go over the board and review any previous work done with a fine tooth comb.

Some of the stuff I've seen done to boards from eBay beggars belief. A little bit of knowledge can be extremely dangerous.
