This build was very fun to put together. There are a few Molex and SATA power connectors that I used from my personal stock. Also it is running Windows 10 Pro for the OS.This was a build that I did for an acquaintances son who is an avid gamer. It has been about 4 months (04/01/2016 Build Date) since he revived it and he is in love with it. I test it out with Bioshock Infinite on the highest graphics settings and it never dropped below 70 FPS. I was also running Kodi on a 2nd screen.
