1 I would get the Asus 7ZS as it is for server purposes, Skulltrail was designed for "Elite Gamers"
As for a cooler, I would go with a Dynatron H185 from Newegg as it is 7$ cheaper, but you will do better with a H46G for cooling, unless you are restricted to a 1u server, if its going to be in a 2u server box, then the H46G will work just fine.
