Since you specifically mentioned anime, some hardware players have half-assed support for some subtitle formats. I have a Popcorn Hour A110 and I moved to HTPC's because of the subtitle issue. Also had some older fansubs (G Gundam, Bt'X, etc) that didn't play nice with the hardware decoder on the PCH. Your PC's pretty overkill just for media playback. Given the 9800 GTX+ only supports VP2 and has pretty high power consumption, I suggest you consider selling it for a lower-power GT 520 or HD 6450.
You could also swap out the Q6700 for a low-power Pentium E5000 or Celeron E3000.
Does my asus motherboard even support either of those CPU's? I can't find any info on it.
It might turn out to cost more than another alternative. Hmmm
Edit: Also, should I cut the mem down to 2 GB too? To reduce power consumption. And will my 550w PSU be a problem?
