Because of that I kept i7-3770K/Z77 FTW Platform until everything is clear with R5E that no more problems.
If I need RMA I only need to put new motherboard with RAM and CPU and to connect 4 cables and tight H100.
Today with many half working and problamtic hardware that's simply necessary, parts are not more reliable and we can't stay with one RIG.
Don't even to talk about back up graphic card/PSU, some cooler...That's necessary.
