Images aren't very clear. Try taking pictures of the sections that appear to have any identifying information(like where stickers exist). Also look on the back of the board. The model number of the PackardBell system you pulled it from might be helpful, if it was the original board it came with. I'm guessing this may have come out of one of the old PackardBell 'Legend' series, but I'd need you to confirm that. Information on the board can potentially be narrowed down, but due to the system age you're probably going to have to go through historical information on the PackardBell model information rather than information directly on the board.
