The structure is like the X51, especially the graphics card placement. I do prefer X51' shape, too bad you can't upgrade motherboard of X51 because of the fixed I/O Shield, or I will buy a used x51 then replace with my z77n-wifi, that could be awesome.
My x58a-ud3r kept i7-960 voltage at 2.0v, then I sent the motherboard to RMA and everything works fine. But~~~~~one pin on the processor melted, I do hope the processor completely down so I can replace a better one :D
