ITX HTPC - Case, Mobo & CPU confusion

I'm folks, I'm looking to build my first HTPC and I'm having some trouble sorting out a few things that I'm hoping you all can help with. This build will be used for the following, in priority order:

- Watching web based video, specifically Hulu & Netflix through Windows 7 Media Center
- Playing BluRay DVDs
- Streaming music from both HD (MP3 & Windows Media lossless) and online services (Rhapsody, etc.)


I'd like to have a fairly small, quiet, low power system and I don't need infinite expandablity. Here are the areas I'm still confused about.

Mobo/CPU - I like the mini-ITX form factor and in looking around I like the look of the Zotac boads because they have wireless and graphics built in. I'm wondering about two specifics in this area:

1. Pros/Cons of going with the Zotac IONITX with the Atom chip (Option 1) versus a Zotac/Wofdale combination (Option 2). I've seen both in the forums but don't have a good feel for how they each behavior. Specific options are blow.


Option 1
Zotac IONITX-A-U Atom N330 Dual Core 90-Watt PSU WiFi ITX Intel Motherboard (9400M integrated graphic with dual core 1.6)

2. Second question is about power, you can get the Zotac borads with or without a 90W power supply. Is it worth going for the on-board power or skip it and use the PS that comes with most the cases?

3. Finally, I haven't really found a case that seems right yet. Most the mini-ITX cases seem to only allow the slim DVD drives, but I have not found any BluRay drives in that format. Any recomendations for cases that fit this system? (Note: Expandability isn't an issue, I'll build a new HTPC if I ever need more functionality.) Cases I'm considering at this point:

Interested in any suggestions for a solid case that can host the full size BluRay DVD player.

The rest of the components are pretty standard per postings I've seen in this forum:
