i was wondering if i was to purchase a motherboard from ebay that is out of the same model as mine, would their be any issues with the operation after or would oit work like normal..for example, i noticed when i was looking for one online, often times in the description was some kind of id or serial number. i noticed their are stickers on the board itself that seems to correlate with the ones listed in the ads. mine always matched theirs except for the final 3 numbers/letters. if i was to buy one, would their be any issues as far as functionality goes?
