Today's (December 27) subscriber email from NewEgg includes a coupon code for 15% discount on selected Supermicro boards. Clicking the link shows many models that I recognize from discussions here, including the X10SL7-F-O.
No point in including the code here, as if you're not a subscriber you can't use it, and if you're already a subscriber but haven't checked your email yet, do so and you'll get the code.
