@JKHOWARD, I agree. HTPC cases that can handle regular GPUs at this point can generally handle full size GPUs, so "mini" GPUs are kind of pointless. I know in my case alone when I saw this article the first thing I thought was maybe I finally upgrade both my HTPCs. Both of which are still using low profile GTX 750 TI, which was the best low profile card I could find at the time.
There are many of cases that need low profile cards out there, not to many that need mini.
