My RE4 is on order, and I'm trying to pick a MB waterblock. It seems that currently there are two companies making them. Koolance #MBASR44 and EK #FB KIT RE4. There are a couple of posts in this thread regarding the Koolance block, but nothing (that I saw) on the EK. Any advice on which is better? I'm concerned about cooling performance and about the location of the rear port on the X79 portion of block. The port seems very close to the top PCI slot and may cause clearance issuse between the compression fitting and the first graphics card. I don't know which one has more clearance. Im new to this forum, so if I'm posting in the wrong place, I appologize in advance and appreciate the appropriate redirection.

Thanks for your help.
