thanks for the help rwpritchett.
Your build and explanation is pretty good.
I won't need a remote since I plan to interact with my HTPC using my smartphone and remote desktop :P
Also, the onboard video is more than enough since i'll only be watching movies and browsing the web, maybe play old games through emulators :P
I will hook it to my logitech Z5500 and hopefully get DTS audio out of it with mkv files I have. I gotta find a mobo that can handle all that. Asus and ASRock are known for good mobos. Just waiting for their FM1 ITX boards now.
