I built this system back in 2011. I upgraded the case, cooler and added some memory in 2013. Since I just built a new PC I am trying to decide whether to use this old one to build a NAS or set it up with Linux in order to learn pen testing.
It still runs great. I removed my GTX 970 from this one to use in my new build until I upgrade the graphics card. I will either re-install the 970 here or just use my old 8800GT once I determine if it still works.
EDIT: I ended up selling this to a friend with the GTX 970. It was a great system that lasted me 8 years.
