OK guys,
a couple months ago when haswell was released I came across an Asus board that was very similar to this http://www.newegg.com/Product/Product.aspx?Item=N82E16813131998
Now some things that stood out about it was that it was not listed as a standard atx form factor board. it was something like AuTX. It also had the 60a blackwing chokes. It was NOT a maximus board, the color scheme was the same as the WS board I posed above.
I remember the price also being at the $175 price point at newegg.
So yea, I cant find this thing anywhere. Checked newegg and googled for nearly an hour trying to find this board! I also double checked the 2 or 3 Asus Z87 vids posted here via youtube.
I know for certain there was a board released at the time, I just cant find it now!
