Monoprice offers the open-box Intel Kaby Lake Core i7-7700K 4.2GHz Quad-Core LGA 1151 Processor for $249.99 with free shipping. That's $28 under last month's mention of a factory-sealed unit and the lowest price we've seen for it in any condition. (It's also $59 below the best deal for a factory-sealed unit today.) It features 8MB of cache memory.
