For sale is a used Supermicro AOC-SAT2-MV8 8-Port SATA Card.
I have two (2) of these for sale. Each will be $20. SATA cables are included in the price.
Shipping will be based on location. I'm guessing $10-$15 for each or both. I also have to find a box to ship them in so it may take me some time to ship them out. Or if you're in the Southern California Orange County area you can pick it up from my house.
