@Zol;
the problem is only mentioned to the X58 classified. The problem here ist that the NB Cooler is too high and near to the CPU socket. Maxiumum high for such coolers is normally 40 mm, but this looks like much more, so the mugen would collide the NB Cooler in vertical position. Its hard to say, but if you have the board allready, please check it with this Data:

From my point of view i can not garantee that a vertical position fits.
On the normal X58 SLi all should fit without problems.
PS: we only can test such boards via google, images and experience in things like this. It is not possible to test all the Motherboards on the Market for physicaly compatibility.

Your board is no Problem for our Mugen 2.
