Hey Zhann, HT only deals with the processor. Raid is what does crazy cool stuff with your hard drives, and you have to have at least two. Raid 0 is definitely a cool setup, especially with hard drives so large. Nice computer! I have my more powerful sub positioned similarly and if I scoot back in my chair I can really start hearing it. I turned up some rap song really loud and I was wondering why the bass wasn't really loud until I left the room and came back. Then I had the sub pointing at me and it actually was pretty loud, you just don't hear it from the side.
