Jumping in late; apologies to all for falling off my own build thread. I will throw myself to the mercy of the crowd given that I'm at the tail end of two weeks in Japan (meh) Vietnam (amazing) and now the PRC (somewhere in between-with 1.3B people) that I didn't take a computer on. Now on the wife's and using a VPN I'm catching up on Asia trying to murder me through amazing food and far too much booze.
So with the vents, I'll be purchasing the Nakatenga vents as soon as I get home for exactly what has been described-i.e. keeping some air flowing as we head fully into East Coat summer. From what I've heard they work fairly well in that role.
As far as purchasing direct vs via SDO, I will go with SDO even if it is a little more. Jason Lavender is a stand up guy, a pillar of the Northern VA Rover community-so I'm biased since he's a friend too.
