I just bought a new i3-7320 on ebay from Newegg for a new HTPC build. I received the package today and the package looks in great shape, has the normal intel stickers and the package was still factory sealed. Now my question is why is the integrated heat spreader marked. It looks almost like a feint rectangle when held in certain light conditions, like a heatsink was installed once. Could this be from the factory tests to make sure it works? I've just never seen this before. Here are some pics. You can see the rectangle outline well in this one.
