If you're looking to add SFP+ anyway this is a great one: Supermicro X10SDV F Xeon D Broadwell de 1540 8 Core Mini ITX Motherboard | eBay Xeon D-1540 for the price of a D-1520.
sent offer of 440 to test the willingness to sell..@dave I wil lsay @MiniKnight did post it as $499 but I edited the title when I clicked through. Too bad nobody got at $499. If that seller would take $499 on the best offer it would be a steal (it even is at this price.)
Someone just bought it..sent offer of 440 to test the willingness to sell..
