Review my HTPC

Here's my initial build, any advice would be greatly appreciated.

Motherboard: P5K-VM
Processor E7200
RAM OCZ 6400 4GB
HDD: Caviar GP 1TB IntelliPower Serial ATA-300 Hard Drive OEM

I'm still looking for a case and video card and would just use the S/PDIF out for audio. Eventually I would add a blu-ray drive and a tuner card to the setup.

Good catch

I didn't realize it was laptop memory.

How about this Corsair 6400 instead.

After a lot of research today, I made some changes. Hopefully this is final.

I was thinking of putting in the 80GB for the OS as HD1 (not HD2), with the assumption that it will speed up the computer since the OS and media are separated. The 80GB seems to be a lot faster too. Is this not the case?
