Caution on the MSI Pro E, we just got one about a week or two ago, and i'm not inclined to use it fully at the moment. The MSIs have been having a heat issue with the IOH/northbridge, mine IDLES at 80ºC with a giant 200mm fan blowing at it (granted I'm on an H50 for the CPU, so there's not much airflow in the region). added a 120mm in the area and it dropped to 71ºC (steadily rising though, its at 75ºC). Need to go out and get a fan to actually blow AT the northbridge heatsink soon.. The quickest way to fix it would be to reseat the IOH heatsink with proper thermal compound or a 3rd party heatsink, as detailed on the MSI forums here. I unfortunately didn't find out about it until after everything was together, so I'm avoiding this method for the time being...
Appreciate the insight and will definitely check while putting it together. I think my Mugen II comes with some free paste so I'll dab that on
