I have been using a Gigabyte GA-7N400S motherboard. Recently, one of the capacitors on it went bad and so I decided to buy a replacement/additional/spare board, second-hand, although I am going to re-cap the Gigabyte one.
Used for only a couple weeks. Perfect condition with everything included. It's a great motherboard. The best Gigabyte X99 board available. $275. The price listed includes shipping. I ship via USPS with signature confirmation.
