HDMI & DD - Do I still need hack with this cable?

I was thinking about purchasing a new Arcade so I can take advantage of the HDMI output. However, then I started reading about the need for a $50 adaptor if you want HDMI to the TV and Optical audio to the reciever. Then I read this and found out that all you have to do is crack open the plastic case that connects the power and audio to the back of the Xbox so you can still connect the HDMI cable.

My question is if anyone has tried this cable from monoprice and, since it's flat to begin with, if it will work without having to hack the cable. Thoughts?

Thanks!

I might end up hacking mine then, but I like the method I posted earlier, as opposed to this one:

I think I'll probably go ahead and order the flat monoprice cable anyway, just to be sure it will fit. The other monoprice HDMI cables I have now are very thick and look thicker than some of the ones I have seen people use with the hack.

Thanks!
