I have listed a Bigfoot Networks Killer K1 Gigabit PCI-E NIC. I bought with my new computer, but due to have 2 video cards i wasn't able to install. It hasn't ever been used, but doesn't have the box due to the company that i had build it didn't send it with everything. I have everything that came with it when it arrived at my house. I'm willing to let this go below the $199 i spent on it. If you have any questions feel free to message.
