Actually, in building my own system, choosing the MB was my favorite part of the building process; always choosing high-quality and board component reliability/longevity over anything else. I still have a few questions though. What will this mean for aftermarket heatsinks/coolers? I never run with the stock Intel/AMD heatsinks, will these coolers be permanently bolted on just like the processor? And for motherboards featuring high-end processors, what will this mean for scenarios where the MB fails but the processor is still good. Will we just have to scrap the two altogether?
