I have been researching about 12k PC for a long time. Here is my estimated part list: http://pcpartpicker.com/p/GLscVn Some of my watercooling parts are not finalize yet but I will most probably settile on copper or metal tubing. My gpu will also be changed to the r9390x not the r9290x I typed in the list. The monitors will also be changed to the samsung 4k freesync monitors. Both my cpu and gpu will be OC.
