my 2nd gaming rig was built around end 2011, beginning 2012. Original parts:
i7 3960X
Asus Rampage IV Extreme (first board had some issues after a few months, this was a replacement board)
4x 4GB Corsair Dominator DDR3 2133Mhz (I believe I started out with this set of RAM, don't recall changing them)
Corsair HX1050 PSU (changed to Seasonic X-1250 a year or two after building system, HX1050 is in one of my other rigs)
2x/3x WD Black (no issue), 120GB Corsair Force GT (swapped to Samsung 250GB SSD a couple years back)
2x PowerColor R9 290X (replaced by 2x GB VEGA64 Gaming OC) the 290X are still working I believe (in storeroom)
I recall having one 1TB WD Blue fail on me, clicking noise followed by HDD not detected in Windows.
