That's is a powerful HTPC and you really don't need the 660ti or 8gb ram for those duties. My HTPC has an i3 with Intel graphics on it and 4gb ram which is more than good enough.
I would consider sticking in a small SSD for your OS, a 2TB HDD to store all your media and recordings and just going with a Blu Ray player but you may have a good use for your burner.
I added an external USB 3.0 2TB HDD drive to mine to back everything up on. When you get your media collection just how you like it it's a big blow for a HDD failure.
