This is a build I did for a friend of mine. Yes it is overkill.
She uses it for gaming and photo editing.
The reason for the drive cage being out and the power cables for the 980ti's going through there was because the cables wouldnt fit between the 980's and the sata slots. The 980's were a little too long for them so i put them around back.
I like to think this one turned out very good.
